Trait Input

pub trait Input:
    Sized
    + Clone
    + Debug
    + Default
    + Deref<Target = str> {
    // Required method
    fn split_at(self, mid: usize) -> (Self, Self);

    // Provided methods
    fn before(self, index: usize) -> Self { ... }
    fn after(self, index: usize) -> Self { ... }
}

This trait represents input that can be parsed by a Parser and/or matched by a Pattern

Its Default impl of the type should return a value that represents empty input, akin to an empty string, ""

Required Methods

fn split_at(self, mid: usize) -> (Self, Self)

A generalisation of str::split_at

Provided Methods

fn before(self, index: usize) -> Self

Equivalent to self.split_at(mid).0, but can be overridden to provide a more optimal implementation

fn after(self, index: usize) -> Self

Equivalent to self.split_at(mid).1, but can be overriden to provide a more optimal implementation

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.
