Struct alacritty::display::window::Replaceable

struct Replaceable<T>(Option<T>);

Struct for safe in-place replacement.

This struct allows easily replacing struct fields that provide self -> Self methods in-place, without having to deal with constantly unwrapping the underlying Option.

Tuple Fields

0: Option<T>

Implementations

impl<T> Replaceable<T>
