Struct StmtBlock 

pub struct StmtBlock { /* private fields */ }

Implementations

impl StmtBlock

pub fn items(&self) -> impl Iterator<Item = SyntaxNode>

Every direct-child statement (LET_STMT/ASSIGN_STMT/EXPR_STMT) AND the tail expression if present, in source order — the untyped escape hatch, same shape as Block::items.

pub fn tail(&self) -> Option<SyntaxNode>

The block’s unterminated trailing expression (blocks-as-values), if one is present — the last child, when its kind is none of the statement-wrapper kinds this grammar can produce as a genuine statement (parser/stmt.rs::stmt_block never emits any node after the tail, so the last child is always the tail when it isn’t one of those). B0.8 Wave B’s four control-flow kinds (IF_STMT/WHILE_STMT/FOR_STMT/UNTIL_STMT) never produce a value and are always fully delimited by their own body/; — same non-tail treatment as the three Wave A kinds, not new behavior. B0.8 Wave B tail (issue #1322) adds RETURN_STMT/BREAK_STMT/ CONTINUE_STMT to this same non-tail set — all three are always ;-terminated in code-ground position (parser/stmt.rs’s return_stmt/break_stmt/continue_stmt), never a bare tail value. The > text prose-line escape (issue #1992) adds PROSE_LINE to the set for the same reason: it never produces a value (parser/stmt.rs::statement’s doc), so a STMT_BLOCK ending in one has no tail expression, not a prose line masquerading as one (review finding F2 — lower_native/lambda.rs’s block.tail() call would otherwise lower it as a lambda’s return value instead of reaching lower_block_item’s loud E129 arm).
