Trait SpanTransformer

pub trait SpanTransformer {
    type Table;
    type Span: Copy;

    // Required methods
    fn token_id_of(table: &mut Self::Table, s: Self::Span) -> SpanId;
    fn span_for_token_id(table: &Self::Table, id: SpanId) -> Self::Span;
}

Required Associated Types

type Table

type Span: Copy
