Struct rmpv::Utf8StringRef

pub struct Utf8StringRef<'a> { /* fields omitted */ }

A non-owning evil twin of Utf8String. Does exactly the same thing except ownership.

Implementations

impl<'a> Utf8StringRef<'a>

pub fn is_str(&self) -> bool

Returns true if the string is valid UTF-8.

pub fn is_err(&self) -> bool

Returns true if the string contains invalid UTF-8 sequence.

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>

Returns the underlying Utf8Error if the string contains invalud UTF-8 sequence, or else None.

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>

Consumes this object, yielding the string if the string is valid UTF-8, or else None.

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>

Converts a Utf8StringRef into a byte vector.
