Struct rustc_mir::borrow_check::nll::region_infer::values::LivenessValues[][src]

pub(crate) struct LivenessValues<N: Idx> {
    elements: Rc<RegionValueElements>,
    points: SparseBitMatrix<N, PointIndex>,
}
🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

When we initially compute liveness, we use a bit matrix storing points for each region-vid.

[src]

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Creates a new set of "region values" that tracks causal information. Each of the regions in num_region_variables will be initialized with an empty set of points and no causal information.

Iterate through each region that has a value in this set.

Adds the given element to the value for the given region. Returns true if the element is newly added (i.e., was not already present).

Adds all the control-flow points to the values for r.

True if the region r contains the given element.

Returns a "pretty" string value of the region. Meant for debugging.
