pub struct Utf8StringRef<'a> { /* private fields */ }
Expand description
A non-owning evil twin of Utf8String
. Does exactly the same thing except ownership.
Implementations§
§impl<'a> Utf8StringRef<'a>
impl<'a> Utf8StringRef<'a>
pub fn as_str(&self) -> Option<&str>
pub fn as_str(&self) -> Option<&str>
Returns the string reference if the string is valid UTF-8, or else None
.
pub fn as_err(&self) -> Option<&Utf8Error>
pub fn as_err(&self) -> Option<&Utf8Error>
Returns the underlying Utf8Error
if the string contains invalud UTF-8 sequence, or
else None
.
pub fn as_bytes(&self) -> &[u8] ⓘ
pub fn as_bytes(&self) -> &[u8] ⓘ
Returns a byte slice of this string contents no matter whether it’s valid or not UTF-8.
pub fn into_string(self) -> Option<String>
pub fn into_string(self) -> Option<String>
Consumes this object, yielding the string if the string is valid UTF-8, or else None
.
pub fn into_str(self) -> Option<&'a str>
pub fn into_str(self) -> Option<&'a str>
Consumes this object, yielding the string reference if the string is valid UTF-8, or else None
.
pub fn into_bytes(self) -> Vec<u8, Global> ⓘ
pub fn into_bytes(self) -> Vec<u8, Global> ⓘ
