pub trait PartialStorageInfoTrait {
// Required method
fn partial_storage_info() -> Vec<StorageInfo>;
}Expand description
Similar to StorageInfoTrait, a trait to give partial information about storage.
This is useful when a type can give some partial information with its generic parameter doesn’t implement some bounds.
Required Methods§
fn partial_storage_info() -> Vec<StorageInfo>
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
