## Installation
Add to your `Cargo.toml`:
```toml
[dependencies]
sarif-to-md-core = "0.1"
```
## Quick Start
```rust
use sarif_to_md_core::{
ReportProcessorBuilder,
generators::SarifMarkdownGenerator,
markdown::MarkdownFormat,
};
use std::fs;
fn main() -> Result<(), Box<dyn std::error::Error>> {
// Read SARIF content
let sarif_content = fs::read_to_string("security-report.sarif")?;
// Build processor
let processor = ReportProcessorBuilder::new()
.generator(SarifMarkdownGenerator::new(
MarkdownFormat::GitHubFlavored,
true // with emoji
))
.content(sarif_content)
.build()?;
// Generate Markdown
let markdown = processor.generate()?;
println!("{}", markdown);
Ok(())
}
```
## API Overview
### Core Types
#### `ReportProcessor<G>`
Main processor for generating Markdown from SARIF reports.
```rust
pub struct ReportProcessor<G: MarkdownGenerator> {
generator: G,
content: String,
}
impl<G: MarkdownGenerator> ReportProcessor<G> {
pub fn new(generator: G, content: String) -> Self;
pub fn generate(self) -> Result<String, Error>;
}
```
#### `ReportProcessorBuilder<G>`
Builder for constructing `ReportProcessor` instances.
```rust
impl ReportProcessorBuilder<()> {
pub fn new() -> Self;
pub fn generator<G: MarkdownGenerator>(self, generator: G)
-> ReportProcessorBuilder<G>;
}
impl<G: MarkdownGenerator> ReportProcessorBuilder<G> {
pub fn content(self, content: String) -> Self;
pub fn build(self) -> Result<ReportProcessor<G>, BuilderError>;
}
```
#### `MarkdownGenerator` Trait
Core trait for implementing custom Markdown generators.
```rust
pub trait MarkdownGenerator {
type Input: DeserializeOwned;
fn generate_markdown_template(&self, report: &Self::Input)
-> Result<String, GeneratorError>;
}
```
### Generators
#### `SarifMarkdownGenerator`
Built-in generator for SARIF reports.
```rust
impl SarifMarkdownGenerator {
pub fn new(
markdown_format: MarkdownFormat,
with_emoji: bool
) -> Self;
}
```
### Markdown Formats
```rust
pub enum MarkdownFormat {
CommonMark, // Standard Markdown
GitHubFlavored, // GitHub Flavored Markdown with HTML
}
```
### Error Types
```rust
pub enum Error {
JsonError(serde_json::Error),
GeneratorError(GeneratorError),
IoError(std::io::Error),
}
pub enum GeneratorError {
TemplateError(askama::Error),
}
pub enum BuilderError {
MissingContent,
}
```
## Advanced Usage
### Custom Generator Implementation
Create your own Markdown generator by implementing the `MarkdownGenerator` trait:
```rust
use sarif_to_md_core::{
markdown::{MarkdownGenerator, GeneratorError},
ReportProcessorBuilder,
};
use serde::Deserialize;
#[derive(Deserialize)]
struct CustomReport {
findings: Vec<Finding>,
}
struct CustomMarkdownGenerator;
impl MarkdownGenerator for CustomMarkdownGenerator {
type Input = CustomReport;
fn generate_markdown_template(&self, report: &Self::Input)
-> Result<String, GeneratorError>
{
let mut markdown = String::from("# Custom Report\n\n");
for finding in &report.findings {
markdown.push_str(&format!("- {}\n", finding.title));
}
Ok(markdown)
}
}
// Use it
let processor = ReportProcessorBuilder::new()
.generator(CustomMarkdownGenerator)
.content(json_content)
.build()?;
```
### Customizing Output Format
```rust
use sarif_to_md_core::{
generators::SarifMarkdownGenerator,
markdown::MarkdownFormat,
};
// GitHub Flavored with collapsible sections
let gfm_generator = SarifMarkdownGenerator::new(
MarkdownFormat::GitHubFlavored,
true // emoji enabled
);
// CommonMark for maximum compatibility
let cm_generator = SarifMarkdownGenerator::new(
MarkdownFormat::CommonMark,
false // no emoji
);
```
### Error Handling
```rust
use sarif_to_md_core::{Error, BuilderError};
match processor.generate() {
Ok(markdown) => println!("{}", markdown),
Err(Error::JsonError(e)) => eprintln!("Invalid JSON: {}", e),
Err(Error::GeneratorError(e)) => eprintln!("Template error: {}", e),
Err(Error::IoError(e)) => eprintln!("IO error: {}", e),
}
```
### Processing Multiple Files
```rust
use std::path::Path;
use sarif_to_md_core::{
ReportProcessorBuilder,
generators::SarifMarkdownGenerator,
markdown::MarkdownFormat,
};
fn process_directory(dir: &Path) -> Result<Vec<String>, Box<dyn std::error::Error>> {
let mut reports = Vec::new();
for entry in std::fs::read_dir(dir)? {
let entry = entry?;
if entry.path().extension().and_then(|s| s.to_str()) == Some("sarif") {
let content = std::fs::read_to_string(entry.path())?;
let processor = ReportProcessorBuilder::new()
.generator(SarifMarkdownGenerator::new(
MarkdownFormat::CommonMark,
false
))
.content(content)
.build()?;
reports.push(processor.generate()?);
}
}
Ok(reports)
}
```
## Template System
The library uses [Askama](https://crates.io/crates/askama) for template rendering. Templates are located in `templates/sarif/`:
- `report.md` - Main report template
- `macros.md` - Reusable template macros
### Template Variables
Templates have access to:
```rust
struct SarifReportTemplate {
runs: Vec<SarifRun>,
timestamp: String,
with_emoji: bool,
is_gfm: bool,
}
struct SarifRun {
tool_name: String,
tool_version: Option<String>,
total_results: usize,
severity_counts: Vec<SeverityCount>,
results: Vec<SarifResultView>,
}
```
## Testing
```bash
# Run all tests
cargo test
# Run with output
cargo test -- --nocapture
# Test specific module
cargo test markdown::sarif
```
## Benchmarking
```bash
# Run benchmarks (requires nightly)
cargo +nightly bench
```

## MSRV (Minimum Supported Rust Version)
This crate requires Rust **1.90** or later.
## Dependencies
- `serde` - Serialization framework
- `serde_json` - JSON parsing
- `serde-sarif` - SARIF format support
- `askama` - Template engine
- `chrono` - Date/time handling
- `thiserror` - Error handling
## Performance Considerations
- **Parsing**: O(n) complexity for SARIF parsing
- **Template Rendering**: O(m) where m is the number of findings
- **Memory**: Minimal allocations, most data is borrowed
- **Throughput**: Can process 1000+ findings per second on modern hardware
