Enum rustc_middle::mir::interpret::GlobalAlloc

source · [−]

pub enum GlobalAlloc<'tcx> {
    Function(Instance<'tcx>),
    Static(DefId),
    Memory(&'tcx Allocation),
}

Expand description

An allocation in the global (tcx-managed) memory can be either a function pointer, a static, or a “real” allocation with some data in it.

Variants

`Function(Instance<'tcx>)`

The alloc ID is used as a function pointer.

`Static(DefId)`

The alloc ID points to a “lazy” static variable that did not get computed (yet). This is also used to break the cycle in recursive statics.

`Memory(&'tcx Allocation)`

The alloc ID points to memory.

Implementations

source

impl<'tcx> GlobalAlloc<'tcx>

source

pub fn unwrap_memory(&self) -> &'tcx Allocation

Panics if the GlobalAlloc does not refer to an GlobalAlloc::Memory

source

pub fn unwrap_fn(&self) -> Instance<'tcx>

Panics if the GlobalAlloc is not GlobalAlloc::Function

source

pub default fn fingerprint_style() -> FingerprintStyle

source

pub default fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous). Read more

source

pub default fn to_debug_str(&self, Ctxt) -> String

source

pub default fn recover(
Ctxt,
&DepNode<<Ctxt as DepContext>::DepKind>
) -> Option<T>

This method tries to recover the query key from the given DepNode, something which is needed when forcing DepNodes during red-green evaluation. The query system will only call this method if fingerprint_style() is not FingerprintStyle::Opaque. It is always valid to return None here, in which case incremental compilation will treat the query as having changed instead of forcing it. Read more
