Enum Context 

enum Context {
    Normal,
    Fn,
    Loop(LoopSource),
    Closure(Span),
    Coroutine {
        coroutine_span: Span,
        kind: CoroutineDesugaring,
        source: CoroutineSource,
    },
    UnlabeledBlock(Span),
    UnlabeledIfBlock(Span),
    LabeledBlock,
    AnonConst,
    ConstBlock,
    LoopMatch {
        labeled_block: Destination,
    },
}

The context in which a block is encountered.

Variants

Normal

Fn

Loop(LoopSource)

Closure(Span)

Coroutine

Fields

coroutine_span: Span

kind: CoroutineDesugaring

source: CoroutineSource

UnlabeledBlock(Span)

UnlabeledIfBlock(Span)

LabeledBlock

AnonConst

E.g. The labeled block inside ['_'; 'block: { break 'block 1 + 2; }].

ConstBlock

E.g. const { ... }.

LoopMatch

E.g. #[loop_match] loop { state = 'label: { /* ... */ } }.

Fields

labeled_block: Destination

The destination pointing to the labeled block (not to the loop itself).

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl PartialEq for Context

fn eq(&self, other: &Context) -> 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 Copy for Context

impl StructuralPartialEq for Context

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
