Struct UndoLabel 

pub struct UndoLabel {
    pub subject: &'static str,
    pub action: &'static str,
}

A stable, machine-readable name for what a command did.

Deliberately not a localized string. This crate is generated and knows nothing about locales or about the application’s translation catalogue, so it hands back a key — ("binder_item", "remove") — and the application turns that into “Undo deleting a scene” in the reader’s language.

Fields

subject: &'static str

What was acted on: an entity name, or a feature use case’s own name.

action: &'static str

What was done to it — "create", "update", "remove", … Empty when subject already names the whole act (a feature use case such as "trash_binder_items" is not an action on something else).

Implementations

impl UndoLabel

pub const fn new(subject: &'static str, action: &'static str) -> Self

pub const fn act(subject: &'static str) -> Self
