Type Alias sc_network_common::sync::message::BlockRequest

pub type BlockRequest<B> = BlockRequest<<B as BlockT>::Hash, <<B as BlockT>::Header as HeaderT>::Number>;

Type alias for using the block request type using block type parameters.

Aliased Type

struct BlockRequest<B> {
    pub id: u64,
    pub fields: BlockAttributes,
    pub from: FromBlock<<B as Block>::Hash, <<B as Block>::Header as Header>::Number>,
    pub direction: Direction,
    pub max: Option<u32>,
}

Fields

id: u64

Unique request id.

fields: BlockAttributes

Bits of block data to request.

from: FromBlock<<B as Block>::Hash, <<B as Block>::Header as Header>::Number>

Start from this block.

direction: Direction

Sequence direction.

max: Option<u32>

Maximum number of blocks to return. An implementation defined maximum is used when unspecified.

Trait Implementations

impl<Hash: Clone, Number: Clone> Clone for BlockRequest<Hash, Number>

fn clone(&self) -> BlockRequest<Hash, Number>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Hash: Debug, Number: Debug> Debug for BlockRequest<Hash, Number>

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

Formats the value using the given formatter.

impl<Hash, Number> Decode for BlockRequest<Hash, Number>

where FromBlock<Hash, Number>: Decode,

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<Hash, Number> Encode for BlockRequest<Hash, Number>

where FromBlock<Hash, Number>: Encode,

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<Hash: PartialEq, Number: PartialEq> PartialEq for BlockRequest<Hash, Number>

fn eq(&self, other: &BlockRequest<Hash, Number>) -> 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.
