Struct rustc_mir_dataflow::points::DenseLocationMap
source · pub struct DenseLocationMap {
statements_before_block: IndexVec<BasicBlock, usize>,
basic_blocks: IndexVec<PointIndex, BasicBlock>,
num_points: usize,
}
Expand description
Maps between a Location
and a PointIndex
(and vice versa).
Fields§
§statements_before_block: IndexVec<BasicBlock, usize>
For each basic block, how many points are contained within?
basic_blocks: IndexVec<PointIndex, BasicBlock>
Map backward from each point to the basic block that it belongs to.
num_points: usize
Implementations§
source§impl DenseLocationMap
impl DenseLocationMap
pub fn new(body: &Body<'_>) -> Self
sourcepub fn num_points(&self) -> usize
pub fn num_points(&self) -> usize
Total number of point indices
sourcepub fn point_from_location(&self, location: Location) -> PointIndex
pub fn point_from_location(&self, location: Location) -> PointIndex
Converts a Location
into a PointIndex
. O(1).
sourcepub fn entry_point(&self, block: BasicBlock) -> PointIndex
pub fn entry_point(&self, block: BasicBlock) -> PointIndex
Returns the PointIndex
for the first statement in the given BasicBlock
. O(1).
sourcepub fn to_block_start(&self, index: PointIndex) -> PointIndex
pub fn to_block_start(&self, index: PointIndex) -> PointIndex
Return the PointIndex for the block start of this index.
sourcepub fn to_location(&self, index: PointIndex) -> Location
pub fn to_location(&self, index: PointIndex) -> Location
Converts a PointIndex
back to a location. O(1).
sourcepub fn point_in_range(&self, index: PointIndex) -> bool
pub fn point_in_range(&self, index: PointIndex) -> bool
Sometimes we get point-indices back from bitsets that may be out of range (because they round up to the nearest 2^N number of bits). Use this function to filter such points out if you like.

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.
