Struct GenericPredicates 

pub struct GenericPredicates<'db> { /* private fields */ }

Implementations

impl<'db> GenericPredicates<'db>

pub fn query_with_diagnostics( db: &'db dyn HirDatabase, def: GenericDefId, ) -> &'db (GenericPredicates<'db>, Option<ThinArc<(), TyLoweringDiagnostic>>)

Resolve the where clause(s) of an item with generics.

Diagnostics are computed only for this item’s predicates, not for parents.

impl<'db> GenericPredicates<'db>

pub fn query( db: &'db dyn HirDatabase, def: GenericDefId, ) -> &'db GenericPredicates<'db>

pub fn query_all( db: &'db dyn HirDatabase, def: GenericDefId, ) -> EarlyBinder<'db, &'db [Clause<'db>]>

pub fn query_own( db: &'db dyn HirDatabase, def: GenericDefId, ) -> EarlyBinder<'db, &'db [Clause<'db>]>

pub fn query_explicit( db: &'db dyn HirDatabase, def: GenericDefId, ) -> EarlyBinder<'db, &'db [Clause<'db>]>

pub fn all_predicates(&self) -> EarlyBinder<'db, &[Clause<'db>]>

pub fn own_predicates(&self) -> EarlyBinder<'db, &[Clause<'db>]>

pub fn explicit_predicates(&self) -> EarlyBinder<'db, &[Clause<'db>]>

Returns the predicates, minus the implicit Self: Trait predicate for a trait.

Trait Implementations

impl<'db> Clone for GenericPredicates<'db>

fn clone(&self) -> GenericPredicates<'db>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for GenericPredicates<'db>

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

Formats the value using the given formatter.

impl<'db> Hash for GenericPredicates<'db>

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<'db> PartialEq for GenericPredicates<'db>

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