Struct ClosureArgs 

pub struct ClosureArgs {
    pub item: ItemRef,
    pub kind: ClosureKind,
    pub fn_sig: PolyFnSig,
    pub upvar_tys: Vec<Ty>,
}

Reflects [ty::ClosureArgs]

Fields

item: ItemRef

kind: ClosureKind

The base kind of this closure. The kinds are ordered by inclusion: any Fn works as an FnMut, and any FnMut works as an FnOnce.

fn_sig: PolyFnSig

The signature of the function that the closure implements, e.g. fn(A, B, C) -> D.

upvar_tys: Vec<Ty>

The set of captured variables. Together they form the state of the closure.

Implementations

impl ClosureArgs

pub fn iter_upvar_borrows(&self) -> impl Iterator<Item = &Ty>

Iterate over the upvars that are borrows with erased regions. These may require allocating fresh regions.

impl ClosureArgs

pub fn sfrom<'tcx, S>(s: &S, def_id: RDefId, from: GenericArgsRef<'tcx>) -> Self

where S: UnderOwnerState<'tcx>,

Trait Implementations

impl Clone for ClosureArgs

fn clone(&self) -> ClosureArgs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClosureArgs

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

Formats the value using the given formatter.

impl Hash for ClosureArgs

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 ClosureArgs

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