Enum ScopeItem 

pub enum ScopeItem<'db> {
    AstModule(AstModule<'db>),
    SymModule(SymModule<'db>),
    Class(SymAggregate<'db>),
    SymFunction(SymFunction<'db>),
}

A ScopeItem defines a name resolution scope.

Variants

AstModule(AstModule<'db>)

A module; for phasing reasons, we sometimes add this to the scope tree as the ast node.

SymModule(SymModule<'db>)

A module

Class(SymAggregate<'db>)

A class or other aggregate

SymFunction(SymFunction<'db>)

A function or method

impl<'db> Ord for ScopeItem<'db>

fn cmp(&self, other: &ScopeItem<'db>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'db> PartialEq for ScopeItem<'db>

fn eq(&self, other: &ScopeItem<'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.

impl<'db> PartialOrd for ScopeItem<'db>

fn partial_cmp(&self, other: &ScopeItem<'db>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'db> ScopeTreeNode<'db> for ScopeItem<'db>

fn direct_super_scope(self, db: &'db dyn Db) -> Option<ScopeItem<'db>>

fn direct_generic_parameters( self, db: &'db dyn Db, ) -> &'db Vec<SymVariable<'db>>

fn into_scope(self, db: &'db dyn Db) -> Scope<'db, 'db>
