Struct ChunkToPatch

pub struct ChunkToPatch {
    pub target_buffer: Option<u32>,
    pub writer_id: Option<u32>,
    pub chunk_id: Option<u32>,
    pub patches: Vec<Patch>,
    pub has_more_patches: Option<bool>,
}

Used to patch chunks that have already been sent to the service. The chunk might not be in the shared memory buffer anymore as it could have been moved by the service in response to a prior CommitDataRequest. It is perfectly valid to patch a chunk that is being notified in the same message (a chunk can show up both in the |changed_pages| and |patches| field within the same CommitDataRequest message). In other words, |chunks_to_patch| is always processed after |chunks_to_move|.

Fields

target_buffer: Option<u32>

writer_id: Option<u32>

{WriterID, ChunkID} uniquely identify a chunk for the current producer.

chunk_id: Option<u32>

patches: Vec<Patch>

List of patches to apply to the given chunk.

has_more_patches: Option<bool>

When true more patches will follow in future requests and the chunk should be still considered as patch-pending. When false the chunk becomes eligible for reading.

Implementations

impl ChunkToPatch

pub fn target_buffer(&self) -> u32

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

pub fn writer_id(&self) -> u32

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

pub fn chunk_id(&self) -> u32

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

pub fn has_more_patches(&self) -> bool

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

Trait Implementations

impl Clone for ChunkToPatch

fn clone(&self) -> ChunkToPatch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChunkToPatch

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

Formats the value using the given formatter.

impl Default for ChunkToPatch

fn default() -> Self

Returns the “default value” for a type.

impl Message for ChunkToPatch

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 ChunkToPatch

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