Struct Snapshot 

pub struct Snapshot {
    pub state: BTreeMap<String, Payload>,
    pub calls: VecDeque<Kept>,
}

A key’s state and remembered calls: the input of each of its runs.

Fields

state: BTreeMap<String, Payload>

JSON values, as their handlers encoded them.

calls: VecDeque<Kept>

Oldest first.

Implementations

impl Snapshot

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

{"state":{...},"calls":[{"id","status","result"|"error"|"result64","at"}]}, fields left out when empty (an empty key is {}).

pub fn decode(p: &[u8]) -> Result<Self>

pub fn prune(&mut self, now_ms: u64)

Keeps the newest call per ID, at most KEPT_CALLS, none older than KEPT_CALL_MS.

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

Formats the value using the given formatter.

impl Default for Snapshot

fn default() -> Snapshot

Returns the “default value” for a type.

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.
