Implementations

source

impl Database

source

pub fn open(path: P) -> Result<Database> where
P: AsRef<Path>,

Creates new database handle.

Arguments

path - database directory

source

pub fn close(&self) -> Result<()>

Closes the inner database

source

pub fn reopen(&self) -> Result<()>

Reopens database at the same location.

source

pub fn insert_blooms<'a, I, B>(&self, from: u64, blooms: I) -> Result<()> where
BloomRef<'a>: From,
I: Iterator<Item = B>,

Inserts one or more blooms into database.

Arguments

from - index of the first bloom that needs to be inserted
blooms - iterator over blooms

source

pub fn filter<'a, B, I, II>(
 &self,
 from: u64,
 to: u64,
 blooms: II
) -> Result<Vec<u64>> where
 BloomRef<'a>: From,
 II: IntoIterator<Item = B, IntoIter = I> + Copy,
 I: Iterator<Item = B>,

Returns indexes of all headers matching given bloom in a specified range.

Arguments

from - index of the first bloom that needs to be checked
to - index of the last bloom that needs to be checked (inclusive range)
blooms - searched pattern
