Trait Implementations

impl Clone for PatternCondition

fn clone(&self) -> PatternCondition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PatternCondition

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

Formats the value using the given formatter.

impl From<PatternCaseNode> for PatternCondition

fn from(o: PatternCaseNode) -> Self

Converts to this type from the input type.

impl From<PatternTypeNode> for PatternCondition

fn from(o: PatternTypeNode) -> Self

Converts to this type from the input type.

impl From<PatternWhenNode> for PatternCondition

fn from(o: PatternWhenNode) -> Self

Converts to this type from the input type.

impl Hash for PatternCondition

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PatternCondition

fn eq(&self, other: &PatternCondition) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
