Struct rustc_middle::mir::Location
source · pub struct Location {
pub block: BasicBlock,
pub statement_index: usize,
}
Expand description
Location
represents the position of the start of the statement; or, if
statement_index
equals the number of statements, then the start of the
terminator.
Fields§
§block: BasicBlock
The block that the location is within.
statement_index: usize
Implementations§
source§impl Location
impl Location
pub const START: Location = _
sourcepub fn successor_within_block(&self) -> Location
pub fn successor_within_block(&self) -> Location
Returns the location immediately after this one within the enclosing block.
Note that if this location represents a terminator, then the resulting location would be out of bounds and invalid.
sourcepub fn is_predecessor_of<'tcx>(
&self,
other: Location,
body: &Body<'tcx>
) -> bool
pub fn is_predecessor_of<'tcx>( &self, other: Location, body: &Body<'tcx> ) -> bool
Returns true
if other
is earlier in the control flow graph than self
.
pub fn dominates( &self, other: Location, dominators: &Dominators<BasicBlock> ) -> bool

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).
default fn to_debug_str(&self, _: Tcx) -> String
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.
