Struct WhileStmt 

pub struct WhileStmt { /* private fields */ }

Implementations

impl WhileStmt

pub fn condition(&self) -> Option<Expr>

pub fn body(&self) -> Option<StmtBlock>

pub fn is_await(&self) -> bool

Whether this is the persistent-await form while await cond { … } (docs/flow-suspension-spec.md §3) rather than a plain while loop. The parser bumps the marker await as a direct IDENT token child (the while keyword is the only other direct IDENT token; the condition lives inside an Expr node, never a bare token), so the presence of an IDENT token spelled await here is the unambiguous marker.
