Struct syn::Path

pub struct Path {
    pub leading_colon: Option<Colon2>,
    pub segments: Punctuated<PathSegment, Colon2>,
}

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

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;
use syn::parse::{Parse, ParseStream, Result};

// 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)?,
        })
    }
}
