Trait Input

pub trait Input: Default {
    type Position: Position;
    type Error: Error<Position = Self::Position>;

    // Required methods
    fn next(
        &self,
        pos: Self::Position,
    ) -> Result<(char, Self::Position), Self::Error>;
    fn next_range(
        &self,
        start: Self::Position,
        counts: u32,
    ) -> Result<(&str, Self::Position), Self::Error>;
    fn error_at(&self, pos: Self::Position, reason: &'static str) -> Self::Error;
}

Required Associated Types

type Position: Position

type Error: Error<Position = Self::Position>

Required Methods

fn next( &self, pos: Self::Position, ) -> Result<(char, Self::Position), Self::Error>

fn next_range( &self, start: Self::Position, counts: u32, ) -> Result<(&str, Self::Position), Self::Error>

fn error_at(&self, pos: Self::Position, reason: &'static str) -> Self::Error

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
