Trait Implementations

impl Clone for SinkFinishCallback

fn clone(&self) -> SinkFinishCallback

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SinkFinishCallback

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SinkFinishCallback

fn deserialize<D>( _deserializer: D, ) -> Result<SinkFinishCallback, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SinkFinishCallback

fn eq(&self, other: &SinkFinishCallback) -> 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.

impl Serialize for SinkFinishCallback

fn serialize<S>( &self, _serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
