Struct lightning::ln::msgs::QueryChannelRange

pub struct QueryChannelRange {
    pub chain_hash: ChainHash,
    pub first_blocknum: u32,
    pub number_of_blocks: u32,
}

A query_channel_range message is used to query a peer for channel UTXOs in a range of blocks. The recipient of a query makes a best effort to reply to the query using one or more ReplyChannelRange messages.

Fields

chain_hash: ChainHash

The genesis hash of the blockchain being queried

first_blocknum: u32

The height of the first block for the channel UTXOs being queried

number_of_blocks: u32

The number of blocks to include in the query results

Implementations

impl QueryChannelRange

pub fn end_blocknum(&self) -> u32

Calculates the overflow safe ending block height for the query.

Overflow returns 0xffffffff, otherwise returns first_blocknum + number_of_blocks.

Trait Implementations

impl Clone for QueryChannelRange

fn clone(&self) -> QueryChannelRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueryChannelRange

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

Formats the value using the given formatter.

impl Hash for QueryChannelRange

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for QueryChannelRange

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

impl Readable for QueryChannelRange

fn read<R: Read>(r: &mut R) -> Result<Self, DecodeError>

Reads a Self in from the given Read.

impl Writeable for QueryChannelRange

fn write<W: Writer>(&self, w: &mut W) -> Result<(), Error>

Writes self out to the given Writer.

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

Writes self out to a Vec<u8>.

fn serialized_length(&self) -> usize

Gets the length of this object after it has been serialized. This can be overridden to optimize cases where we prepend an object with its length.
