Struct charon_lib::ast::types::ClosureInfo

pub struct ClosureInfo {
    pub kind: ClosureKind,
    pub state: Vector<TypeVarId, Ty>,
}

Additional information for closures. We mostly use it in micro-passes like [crate::update_closure_signature].

Fields

kind: ClosureKind

state: Vector<TypeVarId, Ty>

Contains the types of the fields in the closure state. More precisely, for every place captured by the closure, the state has one field (typically a ref).

For instance, below the closure has a state with two fields of type &u32:

pub fn test_closure_capture(x: u32, y: u32) -> u32 {
  let f = &|z| x + y + z;
  (f)(0)
}

Trait Implementations

impl Clone for ClosureInfo

fn clone(&self) -> ClosureInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ClosureInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ClosureInfo

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Drive for ClosureInfo

fn drive<V: Visitor>(&self, visitor: &mut V)

impl DriveMut for ClosureInfo

fn drive_mut<V: VisitorMut>(&mut self, visitor: &mut V)

impl PartialEq for ClosureInfo

fn eq(&self, other: &ClosureInfo) -> 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 ClosureInfo

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 ClosureInfo
