Struct frame_support::traits::StorageInfo [−][src]
pub struct StorageInfo { pub pallet_name: Vec<u8>, pub storage_name: Vec<u8>, pub prefix: Vec<u8>, pub max_values: Option<u32>, pub max_size: Option<u32>, }
Expand description
Metadata about storage from the runtime.
Fields
pallet_name: Vec<u8>
Encoded string of pallet name.
storage_name: Vec<u8>
Encoded string of storage name.
prefix: Vec<u8>
The prefix of the storage. All keys after the prefix are considered part of this storage.
max_values: Option<u32>
The maximum number of values in the storage, or none if no maximum specified.
max_size: Option<u32>
The maximum size of key/values in the storage, or none if no maximum specified.
Trait Implementations

Convert self to a slice and append it to the destination.
Convert self to an owned vector.
fn using_encoded<R, F>(&self, f: F) -> R where
F: FnOnce(&[u8]) -> R,
fn using_encoded<R, F>(&self, f: F) -> R where
F: FnOnce(&[u8]) -> R,
