Fields

statements: Vec<Statement<'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?

List of statements in this block.

terminator: Option<Terminator<'tcx>>

Terminator for this block.

NB. This should generally ONLY be None during construction. Therefore, you should generally access it via the terminator() or terminator_mut() methods. The only exception is that certain passes, such as simplify_cfg, swap out the terminator temporarily with None while they continue to recurse over the set of basic blocks.

is_cleanup: bool

If true, this block lies on an unwind path. This is used during trans where distinct kinds of basic blocks may be generated (particularly for MSVC cleanup). Unwind blocks must only branch to other unwind blocks.

Accessor for terminator.

Terminator may not be None after construction of the basic block is complete. This accessor provides a convenience way to reach the terminator.
