Fields

bb_idx: BasicBlock

Basic block to apply the optimization

bin_op_stmt_idx: usize

Statement index of Eq/Ne assignment that can be removed. None if the assignment can not be removed - i.e the statement is used later on

can_remove_bin_op_stmt: bool

Can remove Eq/Ne assignment

to_switch_on: Place<'tcx>

Place that needs to be switched on. This place is of type integral

branch_value_scalar: Scalar

Constant to use in switch target value

branch_value_ty: Ty<'tcx>

Type of the constant value

op: BinOp

Either Eq or Ne

targets: SwitchTargets

Current targets used in the switch

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

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.
