Struct perfetto_consumer_proto::perfetto::protos::read_buffers_response::Slice

pub struct Slice {
    pub data: Option<Vec<u8>>,
    pub last_slice_for_packet: Option<bool>,
}

Each streaming reply returns one or more slices for one or more trace packets, or even just a portion of it (if it’s too big to fit within one IPC). The returned slices are ordered and contiguous: packets’ slices are not interleaved and slices are sent only once all slices for a packet are available (i.e. the consumer will never see any gap).

Fields

data: Option<Vec<u8>>

last_slice_for_packet: Option<bool>

When true, this is the last slice for the packet. A ReadBufferResponse might have no slices marked as |last_slice_for_packet|==true, in the case of a very large packet that gets chunked into several IPCs (in which case only the last IPC for the packet will have this flag set).

Implementations

impl Slice

pub fn data(&self) -> &[u8]

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

pub fn last_slice_for_packet(&self) -> bool

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

Trait Implementations

impl Clone for Slice

fn clone(&self) -> Slice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Slice

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

Formats the value using the given formatter.

impl Default for Slice

fn default() -> Self

Returns the “default value” for a type.

impl Message for Slice

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 Slice

fn eq(&self, other: &Slice) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
