Fields

mir: &'mir Mir<'tcx>

🔬 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?

The MIR for the function called on this frame.

instance: Instance<'tcx>

🔬 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?

The def_id and substs of the current function

span: Span

🔬 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?

The span of the call site.

return_to_block: StackPopCleanup

🔬 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?

Work to perform when returning from this function

return_place: Place

🔬 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?

The location where the result of the current stack frame should be written to.

locals: IndexVec<Local, LocalValue<AllocId>>

🔬 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?

The list of locals for this stack frame, stored in order as [return_ptr, arguments..., variables..., temporaries...]. The locals are stored as Option<Value>s. None represents a local that is currently dead, while a live local can either directly contain Scalar or refer to some part of an Allocation.

block: BasicBlock

🔬 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?

The block that is currently executed (or will be executed after the above call stacks return).

stmt: usize

🔬 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?

The index of the currently evaluated statement.
