Struct Sidecar 

pub struct Sidecar {
    pub pairs: Vec<(Vec<u8>, u8)>,
    pub filter: Bloom,
}

The sidecar of one sealed bundle.

Fields

pairs: Vec<(Vec<u8>, u8)>

(key, offset in the bundle), sorted, without duplicates.

filter: Bloom

The filter over every key in pairs.

Implementations

impl Sidecar

pub fn build<E: AsRef<[u8]>>(entries: &[E], keys: &KeyFn) -> Self

The sidecar over a bundle’s entries with the log’s key function.

pub fn lookup(&self, key: &[u8]) -> Vec<u8>

Offsets of the entries carrying key, ascending.

pub fn key_range(&self) -> Option<(&[u8], &[u8])>

The smallest and largest key, or nothing for an empty bundle.

pub fn to_bytes(&self) -> Vec<u8>

The sidecar as bytes.

pub fn from_bytes(path: &str, bytes: &[u8]) -> Result<Self>

The sidecar to_bytes wrote.

Trait Implementations

impl Clone for Sidecar

fn clone(&self) -> Sidecar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sidecar

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

Formats the value using the given formatter.

impl PartialEq for Sidecar

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