Struct Username 

pub struct Username(/* private fields */);

A borrowed reference to a basic string slice wrapper A basic example of a wrapper around a String

This type ends in Buf, so the borrowed form of this type will be named Username.

Implementations

impl Username

pub const fn from_str(raw: &str) -> &Self

Transparently reinterprets the string slice as a strongly-typed Username

pub const fn from_static(raw: &'static str) -> &'static Self

Transparently reinterprets the static string slice as a strongly-typed Username

pub fn into_owned(self: Box<Username>) -> UsernameBuf

Converts a Box<Username> into a UsernameBuf without copying or allocating

pub const fn as_str(&self) -> &str

Provides access to the underlying value as a string slice.
