Struct ServiceProviderOptions 

#[non_exhaustive]
pub struct ServiceProviderOptions {
    pub validate_scopes: bool,
}

Options for ServiceCollection::build_with / ServiceCollection::build_async_with.

Defaults match MEDI/ASP.NET Core development-time scope validation: validate_scopes = true. Use ServiceProviderOptions::lenient to allow resolving scoped services from the root provider (pre-0.8 behavior). Options for building a ServiceProvider.

#[non_exhaustive]: construct via ServiceProviderOptions::new and the with_* builder methods (Default equals new()), so future options stay additive.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

validate_scopes: bool

Reject resolving Scoped services from the root provider.

Mirrors MEDI ValidateScopes as enabled by the .NET (ASP.NET Core) host in the Development environment: resolving a scoped service outside a scope is a misconfiguration, because the root caches it for the container lifetime (the “scoped becomes singleton” anti-pattern).

• true (default): get/get_async (and constructor dependencies) return RdiError::ScopedFromRootProvider when they would resolve a Scoped service from the root provider. Infallible lookups (get_optional, get_all, get_all_keyed, try_*) treat such a service as not resolvable at the root. get_owned is exempt for the owned instance itself (it is caller-owned and never enters a scope cache); its transitive dependencies are still validated.
• false: restores rust-dix ≤ 0.7 root-scope behavior (the root provider caches scoped instances and acts as the root scope).

Implementations

impl ServiceProviderOptions

pub fn new() -> ServiceProviderOptions

Strict defaults: validate_scopes = true.

pub fn with_validate_scopes( self, validate_scopes: bool, ) -> ServiceProviderOptions

Set scope validation explicitly.

pub fn lenient() -> ServiceProviderOptions

Convenience preset matching MEDI’s bare BuildServiceProvider(): scope validation disabled (root-scope resolution allowed).
