Enum FunctionKind

pub enum FunctionKind {
    Closure,
    Generator,
    Plain,
}

This exists to distinguish different types of functions, which is necessary because depending on the type of function, the method of requesting its signature from TyCtxt differs.

In addition generators also return true for TyCtxt::is_closure but must request their signature differently. Thus we factor that determination out into this enum.

Implementations

impl FunctionKind

pub fn for_def_id( tcx: TyCtxt<'_>, def_id: DefId, ) -> Result<Self, ErrorGuaranteed>

Trait Implementations

impl Clone for FunctionKind

fn clone(&self) -> FunctionKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for FunctionKind

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