Struct Bloom 

pub struct Bloom(u128);

128-bit bloom filter (k=2 hashes) of items a peer supports.

Content-agnostic: items can be protocol ids, swarm keys, or any other identifier hashable as bytes. Discovery-layer hint, not an authoritative list.

Tuple Fields

0: u128

Implementations

impl Bloom

pub fn add<I: AsRef<[u8]>>(&mut self, item: I)

Insert an item.

pub fn may_contain<I: AsRef<[u8]>>(&self, item: I) -> bool

True if this filter might contain item.

pub fn covers(&self, other: &Self) -> bool

True if every bit set in other is also set in self. An empty other is always covered.

pub fn intersects(&self, other: &Self) -> bool

True if self and other share at least one bit.

pub fn is_empty(&self) -> bool

True if no bit is set.

Trait Implementations

impl<'__de, __Context> BorrowDecode<'__de, __Context> for Bloom

fn borrow_decode<__D: BorrowDecoder<'__de, Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given BorrowDecode.

impl Clone for Bloom

fn clone(&self) -> Bloom

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Bloom

impl Debug for Bloom

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

Formats the value using the given formatter.

impl<__Context> Decode<__Context> for Bloom

fn decode<__D: Decoder<Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given Decode.

impl Default for Bloom

fn default() -> Bloom

Returns the “default value” for a type.

impl Encode for Bloom

fn encode<__E: Encoder>(&self, encoder: &mut __E) -> Result<(), EncodeError>

Encode a given type.

impl Eq for Bloom

impl PartialEq for Bloom

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