Returns the username as a string slice.

pub fn into_inner(self) -> String

Returns the username as a string.

Trait Implementations

impl Clone for Username

fn clone(&self) -> Username

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Username

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Username

fn deserialize<D>( deserializer: D, ) -> Result<Username, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Username

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl FromStr for Username

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Username, <Username as FromStr>::Err>

Parses a string s to return a value of this type.

impl PartialEq for Username

fn eq(&self, other: &Username) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Username

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<String> for Username

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Username, <Username as TryFrom<String>>::Error>

Performs the conversion.

impl Eq for Username
