Struct CompoundStatement 

pub struct CompoundStatement<X: Extension = NoExt> {
    pub label: Option<Ident>,
    pub declarations: ThinVec<Declaration<X>>,
    pub body: ThinVec<Statement<X>>,
    pub end_label: Option<Ident>,
    pub meta: Meta,
}

A [<label>:] BEGIN [<declarations>] [<statements>] END [<label>] compound block.

The declaration prefix is parse-time strict-ordered ({variables, conditions} → cursors → handlers); the body is the trailing statement list, in source order, each element a full Statement. Both the opening label: and the closing END <label> are optional and independent surface tags — a block may carry either, both, or neither; when both are present they must match (a structural check the parser enforces).

Fields

label: Option<Ident>

The opening block label (<label>: before BEGIN); None when unlabelled.

declarations: ThinVec<Declaration<X>>

The DECLARE prefix, in source order (always ahead of body).

body: ThinVec<Statement<X>>

The block’s statement list, in source order.

end_label: Option<Ident>

The closing block label (END <label>); None when the close is bare END.

meta: Meta

Source location and node identity.

Trait Implementations
