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

# Struct std::ffi::OsStr 1.0.0[−][src]

    pub struct OsStr { /* fields omitted */ }

Borrowed reference to an OS string (see `OsString`).

This type represents a borrowed reference to a string in the operating system's preferred representation.

`&OsStr` is to `OsString` as `&str` is to `String`: the former in each pair are borrowed references; the latter are owned strings.

See the module's toplevel documentation about conversions for a discussion on the traits which `OsStr` implements for conversions from/to native representations.

## Methods

###

`impl OsStr`

[src]

####

`pub fn new<S: AsRef<OsStr> + ?Sized>(s: &S) -> &OsStr`

[src]

Coerces into an `OsStr` slice.

# Examples

    use std::ffi::OsStr;

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

####

`pub fn to_str(&self) -> Option<&str>`

[src]

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

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

# Examples

    use std::ffi::OsStr;

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

####

`pub fn to_string_lossy(&self) -> Cow<str>`

[src]

Converts an `OsStr` to a `Cow``<``str``>`.

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

# Examples

Calling `to_string_lossy` on an `OsStr` with valid unicode:

    use std::ffi::OsStr;

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

Had `os_str` contained invalid unicode, the `to_string_lossy` call might have returned `"fo�"`.

####

`pub fn to_os_string(&self) -> OsString`

[src]

Copies the slice into an owned `OsString`.

# Examples

    use std::ffi::{OsStr, OsString};

    let os_str = OsStr::new("foo");
    let os_string = os_str.to_os_string();
    assert_eq!(os_string, OsString::from("foo"));Run

####

`pub fn is_empty(&self) -> bool`

1.9.0
[src]

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

####

`pub fn len(&self) -> usize`

1.9.0
[src]

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

####

`pub fn into_os_string(self: Box<OsStr>) -> OsString`

1.20.0
[src]

Converts a `Box``<OsStr>` into an `OsString` without copying or allocating.

## 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`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
