Struct CaptureName 

pub struct CaptureName(/* private fields */);

The name of a template capture — an identifier by construction.

§4.1 allows Unicode identifiers and the workspace has one character class for them, praxis_syntax::ident::is_ident, which is the predicate here. A private ASCII copy of the rule would leave {λ:int} unrecognized as a named capture, silently reinterpreting the whole body λ:int as the parser expression: a name a consumer cannot accept must be reported, never rewritten into a different name.

Implementations

impl CaptureName

pub fn parse(text: &str) -> Result<Self, InvalidCaptureName>

The only constructor.

Errors

InvalidCaptureName when text is not a §4.1 identifier.

pub fn as_str(&self) -> &str

The name text.
