Enum UsernameLabelState 

pub enum UsernameLabelState {
    Used,
    Ignored,
    Abort,
}

The parse state of a username label.

This can be used to signal that a label was recognised in the case that you wish to fail on labels that weren’t recognised.

Variants

Used

The label was used by this parser.

Note in case multiple parsers are used it should in generally be ok, for multiple to “use” the same label.

Ignored

The label was ignored by this parser, reasons for which are not important here.

A parser-user can choose to error a request in case a label was ignored by its parser.

Abort

Abort the parsing as a state has been reached from which cannot be recovered.

impl Hash for UsernameLabelState

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

impl PartialEq for UsernameLabelState

fn eq(&self, other: &UsernameLabelState) -> 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.
