Struct CreateEncoderParams 

pub struct CreateEncoderParams {
    pub input_details: Option<FormatDetails>,
    pub require_hw: Option<bool>,
    pub codec_specifier: Option<String>,
    /* private fields */
}

Parameters used to request an encoder.

Fields

input_details: Option<FormatDetails>

The format of the uncompressed input data.

This field should be a raw mime_type (e.g. ‘video/raw’) and uncompressed format details for the encoder to use when reading buffers.

To be elibigible an encoder must support the input format.

require_hw: Option<bool>

If true, require that the returned codec is HW-accelerated.

If not set, interpreted as false.

codec_specifier: Option<String>

If set to a value obtained from [fuchsia.mediacodec/DetailedCodecDescription.codec_specifier], the create request will create the specified codec or fail. The client should still set other fields in this table as appropriate, so that the codec factory can ensure that the codec will meet the client’s requirements (and to convey oob_bytes as needed). More than one codec reported by from [fuchsia.mediacodec/DetailedCodecDescription] can have the same codec_specifier iff the underlying implementation is the same. A codec implementation may change its codec_specifier(s) each boot, whether updated to a new implementation version or not.

Trait Implementations

impl Clone for CreateEncoderParams

fn clone(&self) -> CreateEncoderParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CreateEncoderParams

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

Formats the value using the given formatter.

impl<D> Decode<CreateEncoderParams, D> for CreateEncoderParams

where D: ResourceDialect,

fn new_empty() -> CreateEncoderParams

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for CreateEncoderParams

fn default() -> CreateEncoderParams

Returns the “default value” for a type.

impl<D> Encode<CreateEncoderParams, D> for &CreateEncoderParams

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for CreateEncoderParams

fn eq(&self, other: &CreateEncoderParams) -> 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 TypeMarker for CreateEncoderParams

type Owned = CreateEncoderParams

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for CreateEncoderParams

type Borrowed<'a> = &'a CreateEncoderParams

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<CreateEncoderParams as TypeMarker>::Owned, ) -> <CreateEncoderParams as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
