Struct State 

pub struct State { /* private fields */ }

Implementations

impl State

pub fn clear(&mut self) -> Result<(), Error>

impl State

pub fn new() -> Self

pub fn len(&self) -> usize

pub fn merge(&mut self, other: &State) -> Result<MergeResult>

Merge incoming state and track potential version conflicts.

A conflict means the incoming state is stale or incompatible with local tombstone knowledge. Callers may use this signal to trigger a full sync.

pub fn diff(&self, other: &State) -> Result<Vec<StateChange>>

pub fn diff_state(&self, other: &State) -> State

Return a State containing only entries that are newer in other than in self. This is useful for sending compact state diffs.

pub fn resign_signatures<F>(&mut self, signer: F) -> Result<usize>

where F: FnMut(&str, u64, &[u8]) -> Result<Vec<u8>>,

Sign entries missing signatures and return how many signatures were added.

pub fn sketch(&self) -> StateSketch

pub fn omit_tombstones(&self) -> State

Trait Implementations

impl Clone for State

fn clone(&self) -> State

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'de> Deserialize<'de> for State

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Vec<SignerStateEntry>> for State

fn from(v: Vec<SignerStateEntry>) -> State

Converts to this type from the input type.

impl Into<Vec<SignerStateEntry>> for State

fn into(self) -> Vec<SignerStateEntry>

Converts this type into the (usually inferred) input type.

impl Serialize for State

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&[SignerStateEntry]> for State

type Error = Error

The type returned in the event of a conversion error.

fn try_from(v: &[SignerStateEntry]) -> Result<State, Self::Error>

Performs the conversion.
