[−][src]Struct rust_cascade::Cascade

pub struct Cascade<'a> { /* fields omitted */ }

A multi-level cascading Bloom filter.

Methods

impl<'a> Cascade<'a>[src]

pub fn from_bytes(bytes: &'a [u8]) -> Result<Option<Box<Cascade<'a>>>, Error>[src]

Attempts to decode and return a multi-level cascading Bloom filter. NB: Cascade does not take ownership of the given data. This is to facilitate decoding cascading filters backed by memory-mapped files.

Arguments

bytes - The encoded representation of the Bloom filters in this cascade. Starts with 2 little endian bytes indicating the version. The current version is 2. The Python filter-cascade project defines the formats, see https://github.com/mozilla/filter-cascade/blob/v0.3.0/filtercascade/fileformats.py

May be of length 0, in which case None is returned.

pub fn has(&self, entry: &[u8]) -> bool[src]

Determine if the given sequence of bytes is in the cascade.

Arguments

entry - The slice of bytes to test for

pub fn has_internal(&self, entry: &[u8]) -> bool[src]
