Type Alias NamedParseResult 

pub(crate) type NamedParseResult = ParseResult<FxHashMap<MacroRulesNormalizedIdent, NamedMatch>>;

A ParseResult where the Success variant contains a mapping of MacroRulesNormalizedIdents to NamedMatches. This represents the mapping of metavars to the token trees they bind to.

Aliased Type

pub(crate) enum NamedParseResult {
    Success(HashMap<MacroRulesNormalizedIdent, NamedMatch, FxBuildHasher>),
    Failure,
    Ambiguity,
    ErrorReported(ErrorGuaranteed),
}

Variants

Success(HashMap<MacroRulesNormalizedIdent, NamedMatch, FxBuildHasher>)

Parsed successfully.

Failure

Arm failed to match.

Tracker::failure() will be called beforehand.

Ambiguity

The input could be parsed in multiple distinct ways.

Tracker::ambiguity() will be called beforehand.

ErrorReported(ErrorGuaranteed)

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
