Implementations

impl Scope

pub fn new( symbol_generator: SymbolGenerator, parent: Option<Scope>, typ: ScopeType, ) -> Scope

pub fn data(&self) -> Ref<'_, ScopeData>

pub fn data_mut(&self) -> RefMut<'_, ScopeData>

pub fn create_child_scope(&self, typ: ScopeType) -> Scope

pub fn find_nearest_scope<F: Fn(ScopeType) -> bool>( &self, pred: F, ) -> Option<Scope>

Returns the closest self-or-ancestor scope that matches the provided predicate. If no such match is found, None is returned.

pub fn find_furthest_scope<F: Fn(ScopeType) -> bool>( &self, pred: F, ) -> Option<Scope>

Returns the most distant self-or-ancestor scope that matches the provided predicate. If no such match is found, None is returned.

pub fn find_symbol_up_to_with_scope( &self, identifier: Identifier, scope_pred: impl Fn(ScopeType) -> bool, ) -> Option<(Scope, Symbol)>

Returns the matching symbol and associated nearest scope that contains the provided identifier. Once a scope is reached that matches the provided predicate, the search stops after looking in that scope. If no such match is found, None is returned.

pub fn find_symbol_up_to<'b>( &self, identifier: Identifier, scope_pred: impl Fn(ScopeType) -> bool, ) -> Option<Symbol>

Returns the matching symbol in the nearest scope for the provided identifier. Once a scope is reached that matches the provided predicate, the search stops after looking in that scope. If no such match is found, None is returned.

pub fn find_symbol_up_to_nearest_scope_of_type<'b>( &self, identifier: Identifier, scope_type: ScopeType, ) -> Option<Symbol>

Returns the matching symbol in the nearest scope for the provided identifier. Once a scope is reached that matches the provided type, the search stops after looking in that scope. If no such match is found, None is returned.

pub fn find_symbol(&self, identifier: Identifier) -> Option<Symbol>

Returns the matching symbol in the nearest scope for the provided identifier. If no such match is found, None is returned.

Trait Implementations

impl Clone for Scope

fn clone(&self) -> Scope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Hash for Scope

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Scope

fn eq(&self, other: &Self) -> 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.
