Trait for applying ap changes.

Required Methods§

Source

fn apply_known_ap_change(self, ap_change: usize) -> Option<Self>

Attempts to apply ap change, fail on overflow only.

Source

fn can_apply_unknown(&self) -> bool

Can unknown ap change be applied.

Provided Methods§

Source

fn apply_ap_change(self, ap_change: ApChange) -> Result<Self, ApChangeError>

Attempts to apply ap change.

Source

fn unchecked_apply_known_ap_change(self, ap_change: usize) -> Self

This trait is not dyn compatible.

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