Struct std::ffi::OsStr1.0.0 [] [src]

pub struct OsStr { /* fields omitted */ }

Slices into OS strings (see OsString).

Methods

impl OsStr
[src]

Coerces into an OsStr slice.

Examples

use std::ffi::OsStr;

let os_str = OsStr::new("foo");Run

Yields a &str slice if the OsStr is valid Unicode.

This conversion may entail doing a check for UTF-8 validity.

Converts an OsStr to a Cow<str>.

Any non-Unicode sequences are replaced with U+FFFD REPLACEMENT CHARACTER.

Copies the slice into an owned OsString.

Checks whether the OsStr is empty.

Examples

use std::ffi::OsStr;

let os_str = OsStr::new("");
assert!(os_str.is_empty());

let os_str = OsStr::new("foo");
assert!(!os_str.is_empty());Run

Returns the length of this OsStr.

Note that this does not return the number of bytes in this string as, for example, OS strings on Windows are encoded as a list of u16 rather than a list of bytes. This number is simply useful for passing to other methods like OsString::with_capacity to avoid reallocations.

See OsStr introduction for more information about encoding.

Examples

use std::ffi::OsStr;

let os_str = OsStr::new("");
assert_eq!(os_str.len(), 0);

let os_str = OsStr::new("foo");
assert_eq!(os_str.len(), 3);Run
