Implementations

impl<Args, Out> PlanCallback<Args, Out>

where Args: PlanCallbackArgs, Out: PlanCallbackOut,

Trait Implementations

impl<Args, Out> Clone for PlanCallback<Args, Out>

fn clone(&self) -> PlanCallback<Args, Out>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Args, Out> Debug for PlanCallback<Args, Out>

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

Formats the value using the given formatter.

impl<'de, Args, Out> Deserialize<'de> for PlanCallback<Args, Out>

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Args, Out> Hash for PlanCallback<Args, Out>

fn hash<H>(&self, _state: &mut H)

where H: Hasher,

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<Args, Out> PartialEq for PlanCallback<Args, Out>

where Args: PartialEq, Out: PartialEq,

fn eq(&self, other: &PlanCallback<Args, Out>) -> bool

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

const 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<Args, Out> Serialize for PlanCallback<Args, Out>

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.

impl<Args, Out> Eq for PlanCallback<Args, Out>

where Args: Eq, Out: Eq,
