Trait rama::username::UsernameLabelParser

pub trait UsernameLabelParser: Default + Send + Sync + 'static {
    type Error: Into<Box<dyn Error + Send + Sync>>;

    // Required methods
    fn parse_label(&mut self, label: &str) -> UsernameLabelState;
    fn build(self, ext: &mut Extensions) -> Result<(), Self::Error>;
}
Expand description

A parser which can parse labels from a username.

Default is to be implemented for every UsernameLabelParser, as it is what is used to create the parser instances for one-time usage.

Required Associated Types§

type Error: Into<Box<dyn Error + Send + Sync>>

Error which can occur during the building phase.

Required Methods§

fn parse_label(&mut self, label: &str) -> UsernameLabelState

Interpret the label and return whether or not the label was recognised and valid.

UsernameLabelState::Ignored should be returned in case the label was not recognised or was not valid.

fn build(self, ext: &mut Extensions) -> Result<(), Self::Error>

Consume self and store/use any of the relevant info seen.

Object Safety§

This trait is not object safe.
