Enum flo_animation::ElementId

pub enum ElementId {
    Unassigned,
    Assigned(i64),
}

Represents the ID of an element

Variants

Unassigned

ID that has not been assigned

(If this is used in a pending edit log, it will be assigned when the edit log is committed)

Assigned(i64)

An assigned element ID

Methods

impl ElementId

pub fn is_assigned(&self) -> bool

Returns true this element ID is assigned

pub fn is_unassigned(&self) -> bool

Returns true if this edit ID is unassigned

pub fn id(&self) -> Option<i64>

Converts this ID to an option

pub fn assign<AssignFn: FnOnce() -> i64>(self, assign: AssignFn) -> ElementId

If this element is not already assigned, uses the specified function to assign an ID.
