std::path::PrefixComponent - Rust
Description: API documentation for the Rust `PrefixComponent` struct in crate `std`.
Keywords: rust, rustlang, rust-lang, PrefixComponent

# Struct std::path::PrefixComponent 1.0.0 [−] [src]

    pub struct PrefixComponent<'a> { /* fields omitted */ }

A structure wrapping a Windows path prefix as well as its unparsed string representation.

In addition to the parsed `Prefix` information returned by `kind`, `PrefixComponent` also holds the raw and unparsed `OsStr` slice, returned by `as_os_str`.

Instances of this `struct` can be obtained by matching against the `Prefix` variant on `Component`.

Does not occur on Unix.

# Examples

    use std::path::{Component, Path, Prefix};
    use std::ffi::OsStr;

    let path = Path::new(r"c:\you\later\");
    match path.components().next().unwrap() {
        Component::Prefix(prefix_component) => {
            assert_eq!(Prefix::Disk(b'C'), prefix_component.kind());
            assert_eq!(OsStr::new("c:"), prefix_component.as_os_str());
        }
        _ => unreachable!(),
    }Run

## Methods

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
