Methods

impl<'tcx> Statement<'tcx>

pub fn make_nop(&mut self)

🔬 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?

Changes a statement to a nop. This is both faster than deleting instructions and avoids invalidating statement indices in Locations.

pub fn replace_nop(&mut self) -> Self

🔬 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?

Changes a statement to a nop and returns the original statement.
