Struct parsel::ast::CustomIdent

source · [−]

pub struct CustomIdent<K> { /* private fields */ }

Expand description

An identifier which allows customizing the keywords of the language, i.e., which words should be accepted and rejected when parsing.

Implementations

source

This is only defined on Word and not on CustomIdent in general, because this practice prevents users from accidentally creating an invalid identifier (one that is a keyword, as defined by the user).
