Struct jj_lib::dsl_util::AliasesMap

pub struct AliasesMap<P> { /* private fields */ }

Map of symbol and function aliases.

Implementations

impl<P> AliasesMap<P>

pub fn new() -> Self

where P: Default,

Creates an empty aliases map with default-constructed parser.

pub fn insert( &mut self, decl: impl AsRef<str>, defn: impl Into<String>, ) -> Result<(), P::Error>

where P: AliasDeclarationParser,

Adds new substitution rule decl = defn.

Returns error if decl is invalid. The defn part isn’t checked. A bad defn will be reported when the alias is substituted.

pub fn symbol_names(&self) -> impl Iterator<Item = &str>

Iterates symbol names in arbitrary order.

pub fn function_names(&self) -> impl Iterator<Item = &str>

Iterates function names in arbitrary order.

pub fn get_symbol(&self, name: &str) -> Option<(AliasId<'_>, &str)>

Looks up symbol alias by name. Returns identifier and definition text.

pub fn get_function( &self, name: &str, arity: usize, ) -> Option<(AliasId<'_>, &[String], &str)>

Looks up function alias by name and arity. Returns identifier, list of parameter names, and definition text.
