Helper

An expression of owner moved into the helper rule helper.

Fields

helper: String

The helper rule name.

owner: String

The rule the expression was lowered from.

construct: String

The construct the target does not write.

encoding: GrammarLoweringEncoding

Whether the helper accepts the same texts.

note: String

How the helper encodes the construct.

original: GrammarExpr

The expression the helper replaces.

Kind

The target does not keep the kind of rule.

Fields

rule: String

The original rule name.

kind: RuleKind

The original rule kind.

Doc

The target does not keep the documentation of rule verbatim.

Fields

rule: String
