Expand description
A platform agnostic variant of OsStrExt
.
For more information, see the module-level documentation.
Required Methods§
sourcefn assert_from_raw_bytes<'a, S>(string: S) -> Cow<'a, Self>where
S: Into<Cow<'a, [u8]>>,
fn assert_from_raw_bytes<'a, S>(string: S) -> Cow<'a, Self>where S: Into<Cow<'a, [u8]>>,
Converts a byte string into an equivalent platform-native string.
Panics
Panics if the string is not valid for the unspecified encoding used by this crate.
Examples
use std::env;
use std::ffi::OsStr;
use os_str_bytes::OsStrBytes;
let os_string = env::current_exe()?;
let os_bytes = os_string.to_raw_bytes();
assert_eq!(os_string, OsStr::assert_from_raw_bytes(os_bytes));
sourcefn from_raw_bytes<'a, S>(string: S) -> Result<Cow<'a, Self>, EncodingError>where
S: Into<Cow<'a, [u8]>>,
fn from_raw_bytes<'a, S>(string: S) -> Result<Cow<'a, Self>, EncodingError>where S: Into<Cow<'a, [u8]>>,
👎Deprecated: use
assert_from_raw_bytes
instead, or enable the ‘checked_conversions’ featureConverts a byte string into an equivalent platform-native string.
assert_from_raw_bytes
should almost always be used instead. For
more information, see EncodingError
.
Errors
See documentation for EncodingError
.
Examples
use std::env;
use std::ffi::OsStr;
use os_str_bytes::OsStrBytes;
let os_string = env::current_exe()?;
let os_bytes = os_string.to_raw_bytes();
assert_eq!(os_string, OsStr::from_raw_bytes(os_bytes).unwrap());
sourcefn to_raw_bytes(&self) -> Cow<'_, [u8]>
fn to_raw_bytes(&self) -> Cow<'_, [u8]>
Converts a platform-native string into an equivalent byte string.
The returned string will use an unspecified encoding.
Examples
use std::ffi::OsStr;
use os_str_bytes::OsStrBytes;
let string = "foobar";
let os_string = OsStr::new(string);
assert_eq!(string.as_bytes(), &*os_string.to_raw_bytes());
