Struct Snapshot 

pub struct Snapshot {
    pub delete_set: DeleteSet,
    pub state_map: StateVector,
}

Snapshot describes a state of a document store at a given point in (logical) time. In practice it’s a combination of StateVector (a summary of all observed insert/update operations) and a DeleteSet (a summary of all observed deletions).

Fields

delete_set: DeleteSet

Compressed information about all deleted blocks at current snapshot time.

state_map: StateVector

Logical clock describing a current snapshot time.

Implementations

impl Snapshot

pub fn new(state_map: StateVector, delete_set: DeleteSet) -> Snapshot

Trait Implementations

impl Clone for Snapshot

fn clone(&self) -> Snapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Snapshot

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

Formats the value using the given formatter.

impl Decode for Snapshot

fn decode<D>(decoder: &mut D) -> Result<Snapshot, Error>

where D: Decoder,

fn decode_v1(data: &[u8]) -> Result<Self, Error>

Helper function for decoding 1st version of lib0 encoding.

fn decode_v2(data: &[u8]) -> Result<Self, Error>

Helper function for decoding 2nd version of lib0 encoding.

impl Default for Snapshot

fn default() -> Snapshot

Returns the “default value” for a type.

impl Encode for Snapshot

fn encode<E>(&self, encoder: &mut E)

where E: Encoder,

fn encode_v1(&self) -> Vec<u8>

Helper function for encoding 1st version of lib0 encoding.

fn encode_v2(&self) -> Vec<u8>

Helper function for encoding 2nd version of lib0 encoding.

impl PartialEq for Snapshot

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