Struct ConditionalBlock 

pub struct ConditionalBlock { /* private fields */ }

Implementations

impl ConditionalBlock

pub fn is_if(&self) -> bool

pub fn is_match(&self) -> bool

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

The head expression: the if condition or the match subject — CONDITIONAL_BLOCK’s only child node that isn’t an arm/else (family.rs::conditional_block: the expression is parsed directly into this node before the arm(s)).

pub fn as_binding(&self) -> Option<AsBinding>

The as NAME binding (B1b, issue #1475) of the template condition form {if EXPR as NAME: … else: …}, when present. Never set for match — a match head is a subject, not a condition.

pub fn if_arm(&self) -> Option<IfArm>

pub fn else_arm(&self) -> Option<ElseBranch>

pub fn match_arms(&self) -> impl Iterator<Item = MatchArm>

match’s arms — direct children of CONDITIONAL_BLOCK itself (family.rs::match_arm_list opens no wrapper node of its own).
