Struct BackendCapabilities 

pub struct BackendCapabilities {
    pub transactional_enqueue: bool,
    pub durable_jobs: bool,
    pub notifications: bool,
    pub streams: bool,
    pub consumer_groups: bool,
    pub distributed_workers: bool,
    pub ordering: OrderingCapability,
    pub backpressure: BackpressureCapability,
}

Storage backend feature and guarantee declaration.

Capabilities describe what a backend can honestly provide. They are not a marketing matrix: application code can inspect this value when it needs a specific storage guarantee.

Fields

transactional_enqueue: bool

durable_jobs: bool

notifications: bool

streams: bool

consumer_groups: bool

distributed_workers: bool

ordering: OrderingCapability

backpressure: BackpressureCapability

Implementations

impl BackendCapabilities

pub const fn memory() -> Self

pub const fn sqlite() -> Self

pub const fn postgres() -> Self

pub const fn redis() -> Self

pub fn supports_portable_job_api(&self) -> bool

pub const fn semantics(&self) -> Option<BackendSemanticCapabilities>

Returns the detailed profile for an exact built-in capability declaration.

Unknown custom combinations return None instead of being guessed as a built-in backend.
