Enum rustc_span::hygiene::ExpnKind

source · [−]

pub enum ExpnKind {
    Root,
    Macro(MacroKind, Symbol),
    AstPass(AstPass),
    Desugaring(DesugaringKind),
    Inlined,

Expand description

Expansion kind.

Variants

`Root`

No expansion, aka root expansion. Only ExpnId::root() has this kind.

`AstPass(AstPass)`

Transform done by the compiler on the AST.

`Desugaring(DesugaringKind)`

Desugaring done by the compiler during HIR lowering.

`Inlined`

MIR inlining

Implementations

Trait Implementations

source

impl Clone for ExpnKind

source

fn clone(&self) -> ExpnKind

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl Debug for ExpnKind

source

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

Formats the value using the given formatter. Read more

source

fn eq(&self, other: &ExpnKind) -> bool

This method tests for self and other values to be equal, and is used by ==. Read more

1.0.0 · source

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more

Uses borrowed data to replace owned data, usually by cloning. Read more

source

impl<T, U> TryFrom for Twhere
U: Into<T>,

type Error = Infallible

const: unstable · source

fn try_into(self) -> Result<U, >::Error>

Performs the conversion.

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.
