Struct BlockRequest

pub struct BlockRequest {
    pub fields: u32,
    pub direction: i32,
    pub max_blocks: u32,
    pub support_multiple_justifications: bool,
    pub from_block: Option<FromBlock>,
}

Request block data from a peer.

Fields

fields: u32

Bits of block data to request.

direction: i32

Sequence direction. If missing, should be interpreted as “Ascending”.

max_blocks: u32

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

optional

support_multiple_justifications: bool

Indicate to the receiver that we support multiple justifications. If the responder also supports this it will populate the multiple justifications field in BlockData instead of the single justification field.

optional

from_block: Option<FromBlock>

Start from this block.

Implementations

impl BlockRequest

pub fn direction(&self) -> Direction

Returns the enum value of direction, or the default if the field is set to an invalid enum value.

pub fn set_direction(&mut self, value: Direction)

Sets direction to the provided enum value.

Trait Implementations

impl Clone for BlockRequest

fn clone(&self) -> BlockRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockRequest

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

Formats the value using the given formatter.

impl Default for BlockRequest

fn default() -> Self

Returns the “default value” for a type.

impl Message for BlockRequest

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 BlockRequest

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