Expand description

A block ({ .. }).

E.g., { .. } as in fn foo() { .. }.

Fields

stmts: Vec<Stmt>

The statements in the block.

id: NodeIdrules: BlockCheckMode

Distinguishes between unsafe { ... } and { ... }.

span: Spantokens: Option<LazyTokenStream>could_be_bare_literal: bool

The following isn’t a parse error, but will cause multiple errors in following stages.

let x = {
    foo: var
};
