Implementations

impl BufferData

pub fn buffer_id(&self) -> u64

Returns the value of buffer_id, or the default value if buffer_id is unset.

pub fn width(&self) -> u32

Returns the value of width, or the default value if width is unset.

pub fn height(&self) -> u32

Returns the value of height, or the default value if height is unset.

pub fn frame_number(&self) -> u64

Returns the value of frame_number, or the default value if frame_number is unset.

pub fn flags(&self) -> u32

Returns the value of flags, or the default value if flags is unset.

pub fn cached_buffer_id(&self) -> u64

Returns the value of cached_buffer_id, or the default value if cached_buffer_id is unset.

pub fn pixel_format(&self) -> PixelFormat

Returns the enum value of pixel_format, or the default if the field is unset or set to an invalid enum value.

pub fn set_pixel_format(&mut self, value: PixelFormat)

Sets pixel_format to the provided enum value.

pub fn usage(&self) -> u64

Returns the value of usage, or the default value if usage is unset.

Trait Implementations

impl Clone for BufferData

fn clone(&self) -> BufferData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BufferData

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

Formats the value using the given formatter.

impl Default for BufferData

fn default() -> Self

Returns the “default value” for a type.

impl Message for BufferData

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for BufferData

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