Struct Parser

pub struct Parser { /* private fields */ }

Expand description

Parser configuration for transforming bytes into WebAssembly binaries.

Implementations§

impl Parser

pub fn new() -> Parser

Creates a new parser with th default settings.

pub fn generate_dwarf(&mut self, generate: GenerateDwarf) -> &mut Self

Available on crate feature dwarf only.

Indicates that DWARF debugging information should be generated and emitted by default.

Note that DWARF debugging information is only emitted for textual-based modules. For example if a WebAssembly binary is parsed via Parser::parse_bytes this won’t insert new DWARF information in such a binary. Additionally if the text format used the (module binary ...) form then no DWARF information will be emitted.

pub fn parse_file(&self, path: impl AsRef<Path>) -> Result<Vec<u8>>

Equivalent of parse_file but uses this parser’s settings.

pub fn parse_bytes<'a>( &self, path: Option<&Path>, bytes: &'a [u8], ) -> Result<Cow<'a, [u8]>>

Equivalent of parse_bytes but uses this parser’s settings.

The path argument is an optional path to use when error messages are generated.

pub fn parse_str( &self, path: Option<&Path>, wat: impl AsRef<str>, ) -> Result<Vec<u8>>

Equivalent of parse_str but uses this parser’s settings.

The path argument is an optional path to use when error messages are generated.
