Implementations

impl PatternLike

pub fn as_expression(&self) -> Option<Expression>

Convert to the matching Expression variant when this pattern shares a node type with Expression (i.e. it can appear in expression position), otherwise None.

Reproduces exactly the set that serde_json::from_value::<Expression> of the same node would accept: the eight variants below wrap the same inner types as their Expression counterparts (AssignmentPattern included — Expression carries it for error-recovery positions), while the pattern-only variants (ObjectPattern, ArrayPattern, RestElement) are not expressions and yield None.

Trait Implementations

impl Clone for PatternLike

fn clone(&self) -> PatternLike

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PatternLike

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Serialize for PatternLike

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
