Implementations§

Source§

impl WireEnvelope

Source

pub fn encode_zero(out: &mut MaybeUninit<Self>)

Encodes a zero envelope into a slot.

Source

pub fn encode_value_static<E: InternalHandleEncoder + ?Sized, T: Encode<E>>( value: T, encoder: &mut E, out: &mut MaybeUninit<Self>, constraint: <T::Encoded as Constrained>::Constraint, ) -> Result<(), EncodeError>

Encodes a 'static value into an envelope with an encoder.

Source

pub fn encode_value<E: Encoder + ?Sized, T: Encode<E>>( value: T, encoder: &mut E, out: &mut MaybeUninit<Self>, constraint: <T::Encoded as Constrained>::Constraint, ) -> Result<(), EncodeError>

Encodes a value into an envelope with an encoder.

Source

pub fn zero() -> Self

Returns the zero envelope.

Source

pub fn is_encoded_zero(slot: Slot<'_, Self>) -> bool

Returns whether a envelope slot is encoded as zero.

Source

pub fn is_zero(&self) -> bool

Returns whether an envelope is zero.

Source

pub fn decode_unknown_static<D: InternalHandleDecoder + ?Sized>( slot: Slot<'_, Self>, decoder: &mut D, ) -> Result<(), DecodeError>

Decodes and discards a static type in an envelope.

Source

pub fn decode_unknown<D: Decoder + ?Sized>( slot: Slot<'_, Self>, decoder: &mut D, ) -> Result<(), DecodeError>

Decodes and discards an unknown value in an envelope.

Source

pub fn decode_as_static<D: InternalHandleDecoder + ?Sized, T: Decode<D>>( slot: Slot<'_, Self>, decoder: &mut D, constraint: <T as Constrained>::Constraint, ) -> Result<(), DecodeError>

Decodes a value of a known type from an envelope.

Source

pub fn decode_as<D: Decoder + ?Sized, T: Decode<D>>( slot: Slot<'_, Self>, decoder: &mut D, constraint: <T as Constrained>::Constraint, ) -> Result<(), DecodeError>

Decodes a value of a known type from an envelope.

Source

pub unsafe fn deref_unchecked<T>(&self) -> &T

Returns a reference to the contained T.

§Safety

The envelope must have been successfully decoded as a T.

Source

pub unsafe fn read_unchecked<T>(&self) -> T

Returns an Owned to the contained T.

§Safety

The envelope must have been successfully decoded as a T.

Source

pub unsafe fn clone_inline_unchecked<T: Clone>(&self) -> Self

Clones the envelope, assuming that it contains an inline T.

§Safety

The envelope must have been successfully decoded inline as a T.
