Struct ModuleEnv

pub struct ModuleEnv {
    pub(crate) module: BTreeMap<Ident, ModSymbol>,
    pub(crate) attrs: Attrs,
}

The type resolution environment within a specific module

Fields

module: BTreeMap<Ident, ModSymbol>

attrs: Attrs

Implementations

impl ModuleEnv

pub(crate) fn new(attrs: Attrs) -> Self

pub(crate) fn insert( &mut self, name: Ident, symbol: ModSymbol, ) -> Option<ModSymbol>

pub fn get(&self, name: &str) -> Option<&ModSymbol>

Given an item name, fetch it

pub fn iter(&self) -> impl Iterator<Item = (&Ident, &ModSymbol)> + '_

Iterate over all name-item pairs in this module

pub fn names(&self) -> impl Iterator<Item = &Ident> + '_

Iterate over all names in this module

This will occur in a stable lexically sorted order by name

pub fn items(&self) -> impl Iterator<Item = &ModSymbol> + '_

Iterate over all items in this module

This will occur in a stable lexically sorted order by name
