pub struct Path {
pub leading_colon: Option<Colon2>,

}
Expand description
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>
Implementations§
source§impl Path
impl Path
sourcepub fn parse_mod_style(input: &ParseBuffer<'_>) -> Result<Path, Error>
pub fn parse_mod_style(input: &ParseBuffer<'_>) -> Result<Path, Error>
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
ⓘ
use syn::{Path, Result, Token};
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)?,
})
}
}
sourcepub fn is_ident<I>(&self, ident: I) -> boolwhere
Ident: PartialEq<I>,
pub fn is_ident<I>(&self, ident: I) -> boolwhere
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.
