Struct ChunksToMove

pub struct ChunksToMove {
    pub page: Option<u32>,
    pub chunk: Option<u32>,
    pub target_buffer: Option<u32>,
    pub data: Option<Vec<u8>>,
}

When |chunks_to_move| is present, the producer is requesting the service to move the given chunks form the share memory buffer into the central trace buffer(s).

Fields

page: Option<u32>

The 0-based index of the page in the Shared Memory Buffer.

chunk: Option<u32>

The 0-based chunk index [0..13] within the page.

target_buffer: Option<u32>

The target buffer it should be moved onto. The service will check that the producer is allowed to write into that buffer before the move.

data: Option<Vec<u8>>

Sending the chunk data over the wire. Used for transports that don’t support shared memory (e.g. vsock or TCP sockets). In the default case (tracing protocol over a Unix socket), this field is not used and tracing data is stored in the shmem buffer and referenced by the fields above. See |use_shemem_emulation| in the codebase for reference.

Implementations

impl ChunksToMove

pub fn page(&self) -> u32

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

pub fn chunk(&self) -> u32

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

pub fn target_buffer(&self) -> u32

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

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

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

Trait Implementations

impl Clone for ChunksToMove

fn clone(&self) -> ChunksToMove

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChunksToMove

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

Formats the value using the given formatter.

impl Default for ChunksToMove

fn default() -> Self

Returns the “default value” for a type.

impl Message for ChunksToMove

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 ChunksToMove

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