Struct ClaimOverlap 

pub struct ClaimOverlap {
    pub first: String,
    pub second: String,
    pub paths: Vec<(String, String)>,
}

Two live claims of different sessions whose scopes meet, at least one advisory: reported, never refused.

An overlap is information, not a verdict — it is how two workers find out they are in the same place without either being stopped. The meeting paths are listed pairwise rather than summarized, because the useful question is which path of mine meets which path of theirs.

use std::sync::Arc;
use majordomus_cli::mesh::identity::NodeIdentity;
use majordomus_cli::mesh::journal::{ClaimMode, EventBody, Journal, StreamLiveness};
use majordomus_cli::mesh::state::{fold, ClaimOverlap};

let j = Journal::open(Arc::new(NodeIdentity::ephemeral().unwrap()), "0000000000000001",
    "repo".into(), None).unwrap();
for (claim, session, mode) in [
    ("c1", "s1", ClaimMode::Exclusive),
    ("c2", "s2", ClaimMode::Advisory),
] {
    j.append_own(EventBody::ClaimAcquired { claim: claim.into(), session: session.into(),
        scope: vec!["apps".into()], intent: None, mode, issue: None }).unwrap();
}

let state = fold(&j.events(), &|_| StreamLiveness::Own);
let overlap: &ClaimOverlap = &state.overlaps[0];
assert_ne!(overlap.first, overlap.second, "two claims, two sessions");
assert_eq!(overlap.paths, [("apps".to_string(), "apps".to_string())]);

Fields

first: String

The earlier claim’s key.

second: String

The later claim’s key.

paths: Vec<(String, String)>

The paths that meet, as first ↔ second pairs.

Trait Implementations

impl Clone for ClaimOverlap

fn clone(&self) -> ClaimOverlap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClaimOverlap

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ClaimOverlap

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ClaimOverlap

impl JsonSchema for ClaimOverlap

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 ClaimOverlap

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
