Trait scan_rules::scanner::ScanStr

pub trait ScanStr<'a>: Sized {
    type Output;
    fn scan(&mut self, s: &'a str) -> Result<(Self::Output, usize), ScanErrorKind>;
}

This trait defines the interface for runtime scanners.

Runtime scanners must be created before they can be used, but this allows their behaviour to be modified at runtime.

Associated Types

type Output

The type that the implementation scans into.

Required Methods

fn scan(&mut self, s: &'a str) -> Result<(Self::Output, usize), ScanErrorKind>

Perform a scan on the given input.
