Struct Written 

pub struct Written {
    pub key: String,
    pub event: String,
    pub lamport: u64,
    pub durability: Durability,
}

What an operation wrote, as its answer to the caller. Every mesh operation is an event appended to this runtime’s journal, and the caller is handed the three facts it cannot work out for itself: the mesh-wide key of the thing it created, the event that says so, and the Lamport stamp that places it against everyone else’s events.

The key is what a later operation is addressed by — a claim is released by the key its acquisition returned, never by the local name it was given — and the stamp is what a caller waiting for a peer to catch up compares against.

use majordomus_cli::mesh::cooperation::Written;
use majordomus_cli::mesh::journal::{ClaimMode, Durability, SessionInfo};

let session = SessionInfo::named("s1", "cli");
let written: Written = cooperation
    .claim(&session, vec!["docs".into()], None, ClaimMode::Advisory, None)
    .unwrap();
assert!(written.lamport > 0, "placed against every other runtime's events");
assert_eq!(written.durability, Durability::Memory, "this journal has no file");

// and the key it returned is how the claim is addressed from here on
cooperation.release(&written.key).unwrap();

Fields

key: String

<stream>/<local id> of what was created or changed.

event: String

<stream>/<seq> of the event that says so.

lamport: u64

The event’s Lamport stamp.

durability: Durability

Whether the event reached this machine’s disk: synced, memory (a journal with no file, by configuration), or not_durable — held and replicated to peers, not on disk here, and not acknowledged as durable. unknown from an executable that predates it.

Trait Implementations

impl Clone for Written

fn clone(&self) -> Written

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Written

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Written

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Written

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 Serialize for Written

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
