Function Custom

Custom<T = unknown>(
name: string,
metadata?: Readonly<Record<string, unknown>>,
): ParamSource<T>
Binds a value produced by an application-registered resolver.

The resolver is registered under the same name with registerParameterResolver. Replaces the legacy createParameterDecorator, which returned a parameter decorator and has no standard-decorator form.

registerParameterResolver('tenant', (ctx) => ctx.request.tenant);
// …
@Params(Custom<Tenant>('tenant'))
list(tenant: Tenant) { … }
```
