Enum TriggerStep

Source

pub enum TriggerStep {
    Awaiting,
    Fired(Vec<(u32, Vec<u8>)>),
}

Expand description

What one observed token did to a not-yet-triggered grammar.

Variants§

§

Awaiting

Nothing matched. The token was buffered and the grammar is untouched – it is not advanced by unconstrained output.

§

Fired(Vec<(u32, Vec<u8>)>)

A trigger fired. These (token, piece) pairs are what the grammar must now be fed, in order, as if they had been sampled under it. A piece here can be a fragment of the token’s real piece: the token that straddles the match start is truncated to the part at or after it.
