Struct rustc_middle::mir::coverage::ExpressionOperandId [−][src]
pub struct ExpressionOperandId { private: u32, }
An ExpressionOperandId value is assigned directly from either a
CounterValueReference.as_u32() (which ascend from 1) or an ExpressionOperandId.as_u32()
(which descend from u32::MAX). Id value 0
(zero) represents a virtual counter with a
constant value of 0
.

.
impl ExpressionOperandId
[src]
pub const ZERO: Self
[src]
An expression operand for a “zero counter”, as described in the following references:
- https://github.com/rust-lang/llvm-project/blob/rustc/11.0-2020-10-12/llvm/docs/CoverageMappingFormat.rst#counter
- https://github.com/rust-lang/llvm-project/blob/rustc/11.0-2020-10-12/llvm/docs/CoverageMappingFormat.rst#tag
- https://github.com/rust-lang/llvm-project/blob/rustc/11.0-2020-10-12/llvm/docs/CoverageMappingFormat.rst#counter-expressions
This operand can be used to count two or more separate code regions with a single counter,
if they run sequentially with no branches, by injecting the Counter
in a BasicBlock
for
one of the code regions, and inserting CounterExpression
s (“add ZERO to the counter”) in
the coverage map for the other code regions.
