Struct ControlTransfer 

#[non_exhaustive]
pub struct ControlTransfer {
    pub kind: ControlTransferKind,
    pub label: Option<String>,
    pub has_value: bool,
}

Control-transfer shell payload.

Models a control-flow edge that leaves the normal fallthrough path: return, the loop-control verbs next/last/redo, or goto. Targets are preserved by name where statically known; dynamic goto targets are recorded by shape without resolution.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

kind: ControlTransferKind

Transfer verb.

label: Option<String>

Static target label, when the verb names one (next OUTER).

has_value: bool

Whether the transfer carries a value payload (return $x).

Trait Implementations

impl Clone for ControlTransfer

fn clone(&self) -> ControlTransfer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ControlTransfer

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

Formats the value using the given formatter.

impl Eq for ControlTransfer

impl PartialEq for ControlTransfer

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