Struct Signature

pub struct Signature {
    pub params: Vec<ExprVarMemberPath>,
    pub extra_rets: Vec<ExprVarMemberPath>,
    pub return_type: TypeId,
    pub implicits: Vec<TypeId>,
    pub panicable: bool,
    pub location: LocationId,
}

Lowered signature of a function.

Fields

params: Vec<ExprVarMemberPath>

Input params.

extra_rets: Vec<ExprVarMemberPath>

Extra returns - e.g. ref params

return_type: TypeId

Return type.

implicits: Vec<TypeId>

Explicit implicit requirements.

panicable: bool

Panicable.

location: LocationId

Location.

Implementations

impl Signature

pub fn from_semantic(db: &dyn LoweringGroup, value: Signature) -> Self

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl<'a, T: ?Sized + Upcast<dyn LoweringGroup + 'a>> DebugWithDb<T> for Signature

fn fmt(&self, f: &mut Formatter<'_>, other_db: &T) -> Result

fn debug<'me, 'db>(&'me self, db: &'me Db) -> DebugWith<'me, Db>

where Self: Sized + 'me,

fn into_debug<'me, 'db>(self, db: &'me Db) -> DebugWith<'me, Db>

where Self: Sized + 'me,

impl Hash for Signature

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 Signature

fn eq(&self, other: &Signature) -> 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<'a> SemanticRewriter<Signature, DiagnosticAdded> for SubstitutionRewriter<'a>

fn internal_rewrite( &mut self, value: &mut Signature, ) -> Result<RewriteResult, DiagnosticAdded>

fn rewrite(&mut self, value: T) -> Result<T, Error>
