pub struct StorageMetadata {
pub prefix: String,
pub entries: BTreeMap<String, StorageEntryMetadata>,
}Expand description
Metadata for a pallet’s storage.
Contains information about the storage prefix and all storage entries in this pallet.
Fields§
§prefix: StringThe prefix used for all storage items in this pallet.
entries: BTreeMap<String, StorageEntryMetadata>The storage entries in this pallet, keyed by entry name.
Implementations§
Source§impl StorageMetadata
impl StorageMetadata
Sourcepub fn from_v12_meta(md: StorageMetadata, lookup: &mut Types) -> Result<Self>
pub fn from_v12_meta(md: StorageMetadata, lookup: &mut Types) -> Result<Self>
Sourcepub fn from_v13_meta(md: StorageMetadata, lookup: &mut Types) -> Result<Self>
pub fn from_v13_meta(md: StorageMetadata, lookup: &mut Types) -> Result<Self>
Sourcepub fn from_v14_meta(
md: &PalletStorageMetadata<PortableForm>,
types: &PortableRegistry,
) -> Result<Self>
pub fn from_v14_meta( md: &PalletStorageMetadata<PortableForm>, types: &PortableRegistry, ) -> Result<Self>
Sourcepub fn pallet_prefix_hash(&self) -> Vec<u8> ⓘ
pub fn pallet_prefix_hash(&self) -> Vec<u8> ⓘ
Computes the pallet prefix hash, which is the xxhash128 of the pallet’s storage prefix.
§Returns
The xxhash128 of the pallet prefix as a vector of bytes.
Sourcepub fn storage_key(&self, entry_name: &str, keys: &[Vec<u8>]) -> Result<Vec<u8>>
pub fn storage_key(&self, entry_name: &str, keys: &[Vec<u8>]) -> Result<Vec<u8>>
Computes the full storage key for a given entry, given its keys (if any).
This is a convenience method that delegates to the corresponding StorageEntryMetadata.
§Arguments
entry_name- The name of the storage entrykeys- The keys for this storage entry, if it’s a map
§Returns
The complete storage key as a vector of bytes, or an error if the entry doesn’t exist or the provided keys don’t match the storage entry type.
