Struct Username 

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

A validated username.

The character set is restricted to ASCII letters, digits, _, -, and .. This keeps URL substitution naive (no percent-encoding needed) and guards against accidental cross-site normalisation differences. Usernames containing characters outside this set are rejected at construction.

Implementations

impl Username

pub fn new(input: impl Into<String>) -> Result<Self>

Construct a Username, validating its character set and length.

pub fn as_str(&self) -> &str

Borrow the inner string.

Trait Implementations

impl AsRef<str> for Username

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

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

Formats the value using the given formatter.

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

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

Deserialize this value from the given Serde deserializer.

impl Display for Username

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

Formats the value using the given formatter.

impl FromStr for Username

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

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

impl Hash for Username

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Eq for Username

impl StructuralPartialEq for Username
