Variants

Implementations

impl Stub

pub fn resolve_alternate_instance<'tcx>( &self, tcx: TyCtxt<'tcx>, function: Instance<'tcx>, param_env: TypingEnv<'tcx>, at: RustSpan, ) -> Result<Instance<'tcx>, ErrorGuaranteed>

fn indirect_required( &self, tcx: TyCtxt<'_>, def_id: DefId, at: RustSpan, ) -> Result<bool, ErrorGuaranteed>

pub fn apply<'tcx>( &self, tcx: TyCtxt<'tcx>, function: Instance<'tcx>, param_env: TypingEnv<'tcx>, arguments: ArgSlice<'_, 'tcx>, at: RustSpan, ) -> Result<(Instance<'tcx>, CallingConvention<'tcx>), ErrorGuaranteed>

Performs the effects of this model on the provided function.

function is what was to be called but for which a stub exists, arguments are the arguments to that call.

Returns a new instance to call instead and how it should be called.

Trait Implementations

impl Clone for Stub

fn clone(&self) -> Stub

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Stub

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Stub

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Stub

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
