Struct bitcoin::bip158::BlockFilter

pub struct BlockFilter {
    pub content: Vec<u8>,
}

A block filter, as described by BIP 158.

Fields

content: Vec<u8>

Golomb encoded filter

Implementations

impl BlockFilter

pub fn new(content: &[u8]) -> BlockFilter

Creates a new filter from pre-computed data.

pub fn new_script_filter<M, S>( block: &Block, script_for_coin: M, ) -> Result<BlockFilter, Error>

where M: Fn(&OutPoint) -> Result<S, Error>, S: Borrow<Script>,

Computes a SCRIPT_FILTER that contains spent and output scripts.

pub fn filter_header( &self, previous_filter_header: &FilterHeader, ) -> FilterHeader

Computes this filter’s ID in a chain of filters (see BIP 157).

pub fn match_any<I>( &self, block_hash: &BlockHash, query: I, ) -> Result<bool, Error>

where I: Iterator, I::Item: Borrow<[u8]>,

Returns true if any query matches against this BlockFilter.

pub fn match_all<I>( &self, block_hash: &BlockHash, query: I, ) -> Result<bool, Error>

where I: Iterator, I::Item: Borrow<[u8]>,

Returns true if all queries match against this BlockFilter.

Trait Implementations

impl Clone for BlockFilter

fn clone(&self) -> BlockFilter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockFilter

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

Formats the value using the given formatter.

impl PartialEq for BlockFilter

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