A FIDL envelope

Implementations

impl Envelope

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

Encodes a zero envelope into a slot.

pub fn encode_value_static<W: Wire, E: InternalHandleEncoder + ?Sized>( value: impl Encode<W, E>, encoder: &mut E, out: &mut MaybeUninit<Self>, constraint: W::Constraint, ) -> Result<(), EncodeError>

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

pub fn encode_value<W: Wire, E: Encoder + ?Sized>( value: impl Encode<W, E>, encoder: &mut E, out: &mut MaybeUninit<Self>, constraint: W::Constraint, ) -> Result<(), EncodeError>

Encodes a value into an envelope with an encoder.

pub fn zero() -> Self

Returns the zero envelope.

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

Returns whether a envelope slot is encoded as zero.

pub fn is_zero(&self) -> bool

Returns whether an envelope is zero.

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.

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

Decodes and discards an unknown value in an envelope.

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

Decodes a value of a known type from an envelope.

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

Decodes a value of a known type from an envelope.

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.

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.

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.

Trait Implementations

impl Constrained for Envelope

type Constraint = ()

Type of constraint information for this type.

fn validate( _: Slot<'_, Self>, _: Self::Constraint, ) -> Result<(), ValidationError>

Validate a slot of this type against a constraint. Can be called when pointers/envelopes are just presence markers.

impl Wire for Envelope

type Narrowed<'de> = Envelope

The narrowed wire type, restricted to the 'de lifetime.

fn zero_padding(_: &mut MaybeUninit<Self>)

Writes zeroes to the padding for this type, if any.

impl Send for Envelope

impl Sync for Envelope
