Struct FunSig

pub struct FunSig {
    pub is_unsafe: bool,
    pub is_closure: bool,
    pub closure_info: Option<ClosureInfo>,
    pub generics: GenericParams,
    pub inputs: Vec<Ty>,
    pub output: Ty,
}

A function signature.

Fields

is_unsafe: bool

Is the function unsafe or not

is_closure: bool

true if the signature is for a closure.

Importantly: if the signature is for a closure, then:

• the type and const generic params actually come from the parent function (the function in which the closure is defined)
• the region variables are local to the closure

closure_info: Option<ClosureInfo>

Additional information if this is the signature of a closure.

generics: GenericParams

inputs: Vec<Ty>

output: Ty

Trait Implementations

impl AstVisitable for FunSig

fn drive<V: VisitAst>(&self, v: &mut V) -> ControlFlow<V::Break>

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

fn drive_mut<V: VisitAstMut>(&mut self, v: &mut V) -> ControlFlow<V::Break>

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

fn name(&self) -> &'static str

The name of the type, used for debug logging.

fn dyn_visit<T: AstVisitable>(&self, f: impl FnMut(&T))

Visit all occurrences of that type inside self, in pre-order traversal.

fn dyn_visit_mut<T: AstVisitable>(&mut self, f: impl FnMut(&mut T))

Visit all occurrences of that type inside self, in pre-order traversal.

impl Clone for FunSig

fn clone(&self) -> FunSig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FunSig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FunSig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'s, V> Drive<'s, V> for FunSig

where V: Visitor + Visit<'s, Option<ClosureInfo>> + Visit<'s, GenericParams> + Visit<'s, Vec<Ty>> + Visit<'s, Ty>,

fn drive_inner(&'s self, visitor: &mut V) -> ControlFlow<V::Break>

Call v.visit() on the immediate contents of self.

impl<'s, V> DriveMut<'s, V> for FunSig

where V: Visitor + VisitMut<'s, Option<ClosureInfo>> + VisitMut<'s, GenericParams> + VisitMut<'s, Vec<Ty>> + VisitMut<'s, Ty>,

fn drive_inner_mut(&'s mut self, visitor: &mut V) -> ControlFlow<V::Break>

Call v.visit() on the immediate contents of self.

impl<C: AstFormatter> FmtWithCtx<C> for FunSig

fn fmt_with_ctx(&self, ctx: &C) -> String

fn fmt_with_ctx_and_indent(&self, _tab: &str, _ctx: &C) -> String

fn with_ctx<'a>(&'a self, ctx: &'a C) -> impl Display + 'a

Returns a struct that implements Display. This allows the following:

impl<'a> Formatter<&FunSig> for FmtCtx<'a>

fn format_object(&self, x: &FunSig) -> String

impl PartialEq for FunSig

fn eq(&self, other: &FunSig) -> 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 Serialize for FunSig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for FunSig

impl StructuralPartialEq for FunSig
