#
LocString

source

A string literal's decoded BYTES together with its span.

Bytes rather than a String because a Wax string literal is a byte string: \xff is one raw byte, and a data segment may hold arbitrary binary that is not valid UTF-8. Named here rather than written inline in the grammar because the generated token enum has to spell the type.

#
Triple

source

A token with its start and end position — the unit the lexer produces and the parser consumes.

MoonYacc's array input mode expects exactly this shape, so the lexer's output feeds the generated parser with no adaptation.

#
Triples

source

An Array is a collection of values that supports random access and can grow in size.

#
TokenKind::expect_class

source
fn TokenKind::expect_class(self : TokenKind) -> String?

The class label this kind collapses into, if any.

A kind in no class keeps its own spelling from to_expect_string.
