Struct UnprojectableLocals 

struct UnprojectableLocals {
    locals: DenseBitSet<Local>,
}

Set of locals which can only be replaced with another local, instead of an arbitrary place. This is usually because it is used directly as a Local outside of a place (e.g. Index projections).

Fields

locals: DenseBitSet<Local>

Implementations

impl UnprojectableLocals

fn find(body: &Body<'_>) -> DenseBitSet<Local>

Trait Implementations

impl Debug for UnprojectableLocals

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
