Variants

None

For terminators that have no successor, like return.

Single(BasicBlock)

For terminators that a single successor, like goto, and assert without cleanup block.

Double(BasicBlock, BasicBlock)

For terminators that two successors, assert with cleanup block and falseEdge.

AssignOnReturn

Fields

return_: &'mir [BasicBlock]

cleanup: Option<BasicBlock>

The cleanup block, if it exists.

place: CallReturnPlaces<'mir, 'tcx>

Special action for Yield, Call and InlineAsm terminators.

SwitchInt

Fields

targets: &'mir SwitchTargets

discr: &'mir Operand<'tcx>

Special edge for SwitchInt.

Trait Implementations

Formats the value using the given formatter.

impl<'mir, 'tcx> Copy for TerminatorEdges<'mir, 'tcx>

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.
