Struct IngestReport 

pub struct IngestReport {
    pub accepted: u64,
    pub duplicate: u64,
    pub pending: u64,
    pub rejected: BTreeMap<Rejection, u64>,
}

What one ingest did: how many events were stored, how many were deliveries of something already held, how many are waiting for a gap ahead of them, and what was refused and why. Every event handed in is accounted for in exactly one of those, which is what makes a sync round auditable — a peer that sends ten events and is told about ten knows nothing went missing between the wire and the store.

use std::sync::Arc;
use majordomus_cli::mesh::identity::NodeIdentity;
use majordomus_cli::mesh::journal::{EventBody, IngestReport, Journal, SessionInfo};

let a = Journal::open(Arc::new(NodeIdentity::ephemeral().unwrap()), "0000000000000001",
    "repo".into(), None).unwrap();
let b = Journal::open(Arc::new(NodeIdentity::ephemeral().unwrap()), "0000000000000002",
    "repo".into(), None).unwrap();
a.append_own(EventBody::SessionOpened { info: SessionInfo::named("s1", "cli") }).unwrap();

let events = a.missing_for(&b.marks(), 1 << 20);
let first: IngestReport = b.ingest(&events, &|_| Ok(()));
assert_eq!((first.accepted, first.duplicate, first.rejected_total()), (1, 0, 0));

// at-least-once delivery: the same event again is absorbed, and changes nothing
let second = b.ingest(&events, &|_| Ok(()));
assert_eq!((second.accepted, second.duplicate), (0, 1));

Fields

accepted: u64

Newly stored and applied, in stream order.

duplicate: u64

Already held: at-least-once delivery, absorbed.

pending: u64

Held back until the gap before them arrives.

rejected: BTreeMap<Rejection, u64>

Refused, by reason.

Implementations

impl IngestReport

pub fn rejected_total(&self) -> u64

Every refused event, summed over reasons.

Trait Implementations

impl Clone for IngestReport

fn clone(&self) -> IngestReport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IngestReport

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

Formats the value using the given formatter.

impl Default for IngestReport

fn default() -> IngestReport

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for IngestReport

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for IngestReport

impl JsonSchema for IngestReport

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for IngestReport

fn eq(&self, other: &IngestReport) -> 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 IngestReport

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
