Struct interledger_service::Username

pub struct Username(_);

Usernames can be unicode and must be between 2 and 32 characters.

This type applies the following checks/transformations to usernames to ensure uniqueness:

1. NFKC Normalization
2. Checks the string is 2-32 word characters only (no special characters except _)
3. Uses case folding to convert to lowercase in a language-aware manner

Trait Implementations

impl AsRef<str> for Username

fn as_ref(&self) -> &str

Performs the conversion.

impl Clone for Username

fn clone(&self) -> Username

Returns a copy of the value.

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

impl Eq for Username

impl Ord for Username

fn cmp(&self, other: &Username) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)
