Enum ProviderScope 

pub enum ProviderScope {
    Singleton,
    Transient,
    Request,
}

Provider lifetime semantics (NestJS Scope.DEFAULT / Scope.TRANSIENT / Scope.REQUEST analogues).

Set per type via #[injectable(scope = "singleton" | "transient" | "request")] or pass to ProviderRegistry::register_use_factory. Request scope requires the app to call nestrs::NestApplication::use_request_scope.

Docs: mdBook Fundamentals in the repository (docs/src/fundamentals.md).

Variants

Singleton

One instance per application container (default).

Transient

A new instance is created on every injection site / resolution.

Request

One instance per request/task scope (requires request-scope middleware).

Trait Implementations

impl Clone for ProviderScope

fn clone(&self) -> ProviderScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProviderScope

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

Formats the value using the given formatter.

impl PartialEq for ProviderScope

fn eq(&self, other: &ProviderScope) -> 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.
