Struct MirPatch

pub struct MirPatch<'tcx> {
    patch_map: IndexVec<BasicBlock, Option<TerminatorKind<'tcx>>>,
    new_blocks: Vec<BasicBlockData<'tcx>>,
    new_statements: Vec<(Location, StatementKind<'tcx>)>,
    new_locals: Vec<LocalDecl<'tcx>>,
    resume_block: Option<BasicBlock>,
    unreachable_cleanup_block: Option<BasicBlock>,
    unreachable_no_cleanup_block: Option<BasicBlock>,
    terminate_block: Option<(BasicBlock, UnwindTerminateReason)>,
    body_span: Span,
    next_local: usize,
}

This struct represents a patch to MIR, which can add new statements and basic blocks and patch over block terminators.

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.
