Enum AtomicityScope 

#[non_exhaustive]
pub enum AtomicityScope {
    PerCommand,
    PerCase,
    ExplicitGroup {
        group: String,
    },
    ExternalSaga {
        saga: String,
    },
}

How commands are grouped for all-or-nothing execution (spec §13.4).

New grouping strategies are expected, so downstream matches need a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PerCommand

Each command commits alone.

PerCase

All commands on the same case commit together (the default for mutations).

ExplicitGroup

A named group commits together.

Fields

group: String

Group name.

ExternalSaga

The command starts an external saga tracked through the outbox.

Fields

saga: String

Saga name.

Implementations

impl AtomicityScope

pub fn discriminant(&self) -> &'static str

Stable snake-case name of the variant, as it appears in JSON.

pub fn group_name(&self) -> Option<&str>

The group or saga name, for the named scopes.

Trait Implementations

impl Clone for AtomicityScope

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AtomicityScope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AtomicityScope

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

where __D: Deserializer<'de>,

impl Eq for AtomicityScope

impl Hash for AtomicityScope

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

impl JsonSchema for AtomicityScope

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
