[−][src]Struct syn::Path
A path at which a named item is exported: std::collections::HashMap
.
This type is available if Syn is built with the "derive"
or "full"
feature.
Fields
leading_colon: Option<Colon2>
segments: Punctuated<PathSegment, Colon2>
Methods
impl Path
[src]
impl Path
pub fn parse_mod_style(input: ParseStream) -> Result<Self>
[src]
pub fn parse_mod_style(input: ParseStream) -> Result<Self>
Parse a Path
containing no path arguments on any of its segments.
This function is available if Syn is built with the "parsing"
feature.
Example
#[macro_use] extern crate syn; use syn::{Path, Result}; use syn::parse::{Parse, ParseStream}; // A simplified single `use` statement like: // // use std::collections::HashMap; // // Note that generic parameters are not allowed in a `use` statement // so the following must not be accepted. // // use a::<b>::c; struct SingleUse { use_token: Token![use], path: Path, } impl Parse for SingleUse { fn parse(input: ParseStream) -> Result<Self> { Ok(SingleUse { use_token: input.parse()?, path: input.call(Path::parse_mod_style)?, }) } }
pub fn is_ident<I>(&self, ident: I) -> bool where
Ident: PartialEq<I>,
[src]
pub fn is_ident<I>(&self, ident: I) -> bool where
Ident: PartialEq<I>,
Determines whether this is a path of length 1 equal to the given ident.
For them to compare equal, it must be the case that:
- the path has no leading colon,
- the number of path segments is 1,
- the first path segment has no angle bracketed or parenthesized path arguments
- and the ident of the first path segment is equal to the given one.

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S
is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
