Struct ScopeChain 

struct ScopeChain<'scope, 'db> {
    kind: ScopeChainKind<'scope, 'db>,
    next: Option<Box<ScopeChain<'scope, 'db>>>,
}

A link in the scope resolution chain. We first attempt to resolve an identifier in the associated ScopeChainKind and, if nothing is found, proceed to the next link.

Fields

kind: ScopeChainKind<'scope, 'db>

Kind of this link.

next: Option<Box<ScopeChain<'scope, 'db>>>

Next link in the chain. Earlier links shadow later links.

Implementations

impl<'scope, 'db> ScopeChain<'scope, 'db>

fn primitives() -> Self

Creates the base of the name resolution chain (primitive types).

pub fn iter(&self) -> impl Iterator<Item = &ScopeChain<'scope, 'db>>

Walks the chain, starting with the innermost links.

fn resolve_name( &self, db: &'db dyn Db, id: Identifier<'db>, ) -> Option<NameResolution<'db>>

fn internal_module_item( &self, _db: &'db dyn Db, sym: impl ScopeTreeNode<'db> + Into<NameResolutionSym<'db>> + Copy, ) -> NameResolution<'db>

Resolve an identifier like x that we mapped to some item in a module.

fn binds_symbol(&self, _db: &'db dyn Db, sym: SymVariable<'db>) -> bool

Trait Implementations

impl<'scope, 'db> Clone for ScopeChain<'scope, 'db>

fn clone(&self) -> ScopeChain<'scope, 'db>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'scope, 'db> Debug for ScopeChain<'scope, 'db>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'scope, 'db> PartialEq for ScopeChain<'scope, 'db>

fn eq(&self, other: &ScopeChain<'scope, 'db>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
