Struct darling::util::IdentList
[−]
[src]
pub struct IdentList(_);
A list of syn::Ident instances. This type is used to extract a list of words from an
attribute.
Usage
An IdentList field on a struct implementing FromMetaItem will turn #[builder(derive(Debug, Clone))] into:
StructOptions { derive: IdentList(vec![syn::Ident::new("Debug"), syn::Ident::new("Clone")]) }
Methods
impl IdentList[src]
pub fn new<T>(vals: Vec<T>) -> IdentList where
T: Into<Ident>, [src]
T: Into<Ident>,
Create a new list.
pub fn as_strs(&'a self) -> Vec<&'a str>[src]
Creates a view of the contained identifiers as &strs.
Methods from Deref<Target = Vec<Ident>>
pub fn capacity(&self) -> usize1.0.0[src]
Returns the number of elements the vector can hold without reallocating.
Examples
let vec: Vec<i32> = Vec::with_capacity(10); assert_eq!(vec.capacity(), 10);
pub fn as_slice(&self) -> &[T]1.7.0[src]
Extracts a slice containing the entire vector.
Equivalent to &s[..].
Examples
use std::io::{self, Write}; let buffer = vec![1, 2, 3, 5, 8]; io::sink().write(buffer.as_slice()).unwrap();
pub fn len(&self) -> usize1.0.0[src]
Returns the number of elements in the vector, also referred to as its 'length'.
Examples
let a = vec![1, 2, 3]; assert_eq!(a.len(), 3);
pub fn is_empty(&self) -> bool1.0.0[src]
Returns true if the vector contains no elements.
Examples
let mut v = Vec::new(); assert!(v.is_empty()); v.push(1); assert!(!v.is_empty());
Trait Implementations
impl Default for IdentList[src]
impl Deref for IdentList[src]
type Target = Vec<Ident>
The resulting type after dereferencing.
fn deref(&self) -> &<IdentList as Deref>::Target[src]
Dereferences the value.
impl Eq for IdentList[src]
impl PartialEq<IdentList> for IdentList[src]
fn eq(&self, __arg_0: &IdentList) -> bool[src]
This method tests for self and other values to be equal, and is used by ==. Read more
fn ne(&self, __arg_0: &IdentList) -> bool[src]
This method tests for !=.
impl FromMetaItem for IdentList[src]
fn from_list(v: &[NestedMeta]) -> Result<IdentList, Error>[src]
Create an instance from a list of nested meta items.
fn from_nested_meta_item(item: &NestedMeta) -> Result<Self, Error>[src]
fn from_meta_item(item: &Meta) -> Result<Self, Error>[src]
Create an instance from a syn::Meta by dispatching to the format-appropriate trait function. This generally should not be overridden by implementers. Read more
fn from_word() -> Result<Self, Error>[src]
Create an instance from the presence of the word in the attribute with no additional options specified. Read more
fn from_value(value: &Lit) -> Result<Self, Error>[src]
Create an instance from a literal value of either foo = "bar" or foo("bar"). This dispatches to the appropriate method based on the type of literal encountered, and generally should not be overridden by implementers. Read more
fn from_char(value: char) -> Result<Self, Error>[src]
Create an instance from a char literal in a value position.
fn from_string(value: &str) -> Result<Self, Error>[src]
Create an instance from a string literal in a value position.
fn from_bool(value: bool) -> Result<Self, Error>[src]
Create an instance from a bool literal in a value position.
impl From<Vec<Ident>> for IdentList[src]
impl Clone for IdentList[src]
fn clone(&self) -> IdentList[src]
Returns a copy of the value. Read more
fn clone_from(&mut self, source: &Self)1.0.0[src]
Performs copy-assignment from source. Read more
