Struct alacritty::display::Replaceable
source · struct Replaceable<T>(Option<T>);
Expand description
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
.
