impl ExprId
sourcepub const MAX_AS_U32: u32 = 4_294_967_040u32
pub const MAX_AS_U32: u32 = 4_294_967_040u32
Maximum value the index can take, as a u32
.
sourcepub const fn from_usize(value: usize) -> Self
pub const fn from_usize(value: usize) -> Self
sourcepub const unsafe fn from_u32_unchecked(value: u32) -> Self
pub const unsafe fn from_u32_unchecked(value: u32) -> Self
Creates a new index from a given u32
.
Safety
The provided value must be less than or equal to the maximum value for the newtype. Providing a value outside this range is undefined due to layout restrictions.
Prefer using from_u32
.

default fn fingerprint_style() -> FingerprintStyle
source§default fn to_fingerprint(&self, tcx: Tcx) -> Fingerprint
default fn to_fingerprint(&self, tcx: Tcx) -> 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).

source§default fn recover(_: Tcx, _: &DepNode) -> Option<T>
default fn recover(_: Tcx, _: &DepNode) -> Option<T>
This method tries to recover the query key from the given
DepNode
,
something which is needed when forcing DepNode
s 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.source§impl<P> IntoQueryParam<P> for P

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.
