Struct CachedPieceByIndexRequest

pub struct CachedPieceByIndexRequest {
    pub piece_index: PieceIndex,
    pub cached_pieces: Arc<Vec<PieceIndex>>,
}

Cached-piece-by-index request.

This is similar to PieceByIndexRequest, but will only respond with cached pieces.

Fields

piece_index: PieceIndex

Request key - piece index

cached_pieces: Arc<Vec<PieceIndex>>

Additional pieces that requester is interested in if they are cached locally

Implementations

impl CachedPieceByIndexRequest

pub const RECOMMENDED_LIMIT: usize = 128usize

Max number of cached piece indexes to accept per request, equals to the number of source shards in a sector and fits nicely into a single TCP packet

Trait Implementations

impl Clone for CachedPieceByIndexRequest

fn clone(&self) -> CachedPieceByIndexRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CachedPieceByIndexRequest

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

Formats the value using the given formatter.

impl Decode for CachedPieceByIndexRequest

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for CachedPieceByIndexRequest

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

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

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl GenericRequest for CachedPieceByIndexRequest

const PROTOCOL_NAME: &'static str = "/subspace/cached-piece-by-index/0.1.0"

Defines request-response protocol name.

const LOG_TARGET: &'static str = "cached-piece-by-index-request-response-handler"

Specifies log-parameters for tracing.

type Response = CachedPieceByIndexResponse

Response type that corresponds to this request

impl PartialEq for CachedPieceByIndexRequest

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