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

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
