Struct CaseArm
pub struct CaseArm { /* private fields */ }Description
One explicit qualified enum-tag pattern and its authored result expression.
Implementations§
§impl CaseArm
impl CaseArm
pub fn resolved_pattern(&self) -> Option<&ValueLiteral>
pub fn resolved_pattern(&self) -> Option<&ValueLiteral>
Exact enum member selected by this pattern after lexical checking.
pub const fn pattern(&self) -> &NamePath
pub const fn pattern(&self) -> &NamePath
Qualified enum tag, resolved against the scrutinee’s exact enum identity.
pub const fn value(&self) -> &Expr
pub const fn value(&self) -> &Expr
Result for this tag; retained until every arm has been validated.
