Struct DeclaredDependency 

pub struct DeclaredDependency {
    pub type_id: fn() -> TypeId,
    pub type_name: &'static str,
}

A dependency declaration collected at link time via inventory.

Available when the validation feature is enabled.

Each #[derive(Injectable)] struct registers one DeclaredDependency entry per field type. Container::validate iterates all collected entries at startup to confirm every required type is present.

You rarely construct this manually; use declare_dependency! instead.

Fields

type_id: fn() -> TypeId

A function pointer returning the TypeId of the required type. Stored as a fn pointer rather than a value because TypeId is not usable in const contexts on stable/nightly without a feature flag.

type_name: &'static str

Human-readable name of the type, produced by stringify!.
