Enum Data 

pub enum Data {
    None,
    Raw(BoundedVec<u8, ConstU32<32>>),
    BlakeTwo256([u8; 32]),
    Sha256([u8; 32]),
    Keccak256([u8; 32]),
    ShaThree256([u8; 32]),
}

Either underlying data blob if it is at most 32 bytes, or a hash of it. If the data is greater than 32-bytes then it will be truncated when encoding.

Can also be None.

Variants

None

No data here.

Raw(BoundedVec<u8, ConstU32<32>>)

The data is stored directly.

BlakeTwo256([u8; 32])

Only the Blake2 hash of the data is stored. The preimage of the hash may be retrieved through some hash-lookup service.

Sha256([u8; 32])

Only the SHA2-256 hash of the data is stored. The preimage of the hash may be retrieved through some hash-lookup service.

Keccak256([u8; 32])

Only the Keccak-256 hash of the data is stored. The preimage of the hash may be retrieved through some hash-lookup service.

ShaThree256([u8; 32])

Only the SHA3-256 hash of the data is stored. The preimage of the hash may be retrieved through some hash-lookup service.

Implementations

impl Data

pub fn is_none(&self) -> bool

Trait Implementations

impl Clone for Data

fn clone(&self) -> Data

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Data

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

Formats the value using the given formatter.

impl Decode for Data

fn decode<I: Input>(input: &mut I) -> 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 Default for Data

fn default() -> Self

Returns the “default value” for a type.

impl Encode for Data

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

Convert self to an owned vector.

fn size_hint(&self) -> usize

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

fn encode_to<T>(&self, dest: &mut T)

where T: Output + ?Sized,

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

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 MaxEncodedLen for Data

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl PartialEq for Data

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl TypeInfo for Data

type Identity = Data

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl DecodeWithMemTracking for Data

impl EncodeLike for Data

impl Eq for Data

impl StructuralPartialEq for Data
