Enum Presence 

pub enum Presence {
    Always,
    When(Trigger),
    Unknown {
        frames: Vec<String>,
    },
}

Whether a frame has a step.

Variants

Always

Every frame has it.

When(Trigger)

A frame has it where the condition holds, as the source’s recorded frames show.

Unknown

Some frames have it and what decides it is not known: the recorded frames that had it (the source’s names for them), so that a consumer can say why it drew or skipped the step. Never empty.

Fields

frames: Vec<String>
