Implementations

impl ShadowVariableKind

pub fn requires_listener(&self) -> bool

pub fn is_automatic(&self) -> bool

pub fn is_piggyback(&self) -> bool

Returns true if this shadow variable piggybacks on another shadow variable’s listener rather than having its own.

Trait Implementations

impl Clone for ShadowVariableKind

fn clone(&self) -> ShadowVariableKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShadowVariableKind

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

Formats the value using the given formatter.

impl Hash for ShadowVariableKind

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 ShadowVariableKind

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

Tests for self and other values to be equal, and is used by ==.

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

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