Struct rustc_hir::Block

pub struct Block<'hir> {
    pub stmts: &'hir [Stmt<'hir>],
    pub expr: Option<&'hir Expr<'hir>>,
    pub hir_id: HirId,
    pub rules: BlockCheckMode,
    pub span: Span,
    pub targeted_by_break: bool,
}

A block of statements { .. }, which may have a label (in this case the targeted_by_break field will be true) and may be unsafe by means of the rules being anything but DefaultBlock.

Fields

stmts: &'hir [Stmt<'hir>]

Statements in a block.

expr: Option<&'hir Expr<'hir>>

An expression at the end of the block without a semicolon, if any.

hir_id: HirId

rules: BlockCheckMode

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

span: Span

targeted_by_break: bool

If true, then there may exist break 'a values that aim to break out of this block early. Used by 'label: {} blocks and by try {} blocks.
