pub trait Recognizable<'a, T, V>: MatchSize {
    // Required method
    fn recognize(self, scanner: &mut Scanner<'a, T>) -> ParseResult<Option<V>>;
}

A trait that defines how to recognize an object.

Type Parameters

• V - The type of the object to recognize
• T - The type of the data to scan
• 'a - The lifetime of the data to scan

Required Methods

fn recognize(self, scanner: &mut Scanner<'a, T>) -> ParseResult<Option<V>>

Try to recognize the object for the given scanner.

Type Parameters

V - The type of the object to recognize

Arguments

• scanner - The scanner to recognize the object for.

Returns

• Ok(Some(V)) if the object was recognized,
• Ok(None) if the object was not recognized,
• Err(ParseError) if an error occurred
