Struct State 

pub struct State {
    pub shards: u32,
    pub timelines: Vec<Timeline>,
}

Fields

shards: u32

timelines: Vec<Timeline>

Implementations

impl State

pub fn timeline(&self, id: &str) -> Option<&Timeline>

pub fn apply(&mut self, e: &Event) -> Result<(), String>

Applies one event; fails on an event that does not fit (a damaged or foreign manifest).

pub fn keys(&self) -> BTreeSet<String>

Every object the state names.

impl State

pub fn retain( &mut self, now_ms: u64, window_ms: u64, current: Option<Current<'_>>, ) -> Vec<String>

Drops restore points older than window_ms (and thins old ones), then every entry no remaining point needs. Returns the keys of the objects dropped. The timeline being written keeps what its next restore point needs.

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 Debug for State

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

Formats the value using the given formatter.

impl Default for State

fn default() -> State

Returns the “default value” for a type.

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 PartialEq for State

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

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.
