Struct frame_support::traits::StorageInfo

pub struct StorageInfo {
    pub pallet_name: Vec<u8>,
    pub storage_name: Vec<u8>,

    pub max_values: Option<u32>,
    pub max_size: Option<u32>,
}

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

impl Clone for StorageInfo

fn clone(&self) -> StorageInfo

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StorageInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Decode for StorageInfo

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for StorageInfo

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl PartialEq for StorageInfo

fn eq(&self, other: &StorageInfo) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeInfo for StorageInfo

type Identity = StorageInfo

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
