Variants§

§

Legacy

A hash with no preimage length. We do not support creation of this except for transitioning from legacy state. In the future we will make this a pure Dummy item storing only the final dummy field.

Fields

§hash: H::Output
§dummy: PhantomData<T>
§

Inline(BoundedInline)

A an bounded Call. Its encoding must be at most 128 bytes.

§

Lookup

A hash of the call together with an upper limit for its size.`

Fields

§hash: H::Output
§len: u32

Implementations§

source§

impl<T, H: Hash> Bounded<T, H>

source

pub fn transmute<S: Encode>(self) -> Bounded<S, H>
where T: Encode + EncodeLike<S>,

Casts the wrapped type into something that encodes alike.

§Examples
use frame_support::{traits::Bounded, sp_runtime::traits::BlakeTwo256};

// Transmute from `String` to `&str`.
let x: Bounded<String, BlakeTwo256> = Bounded::Inline(Default::default());
let _: Bounded<&str, BlakeTwo256> = x.transmute();
source

pub fn hash(&self) -> H::Output

Returns the hash of the preimage.

The hash is re-calculated every time if the preimage is inlined.

source

pub fn lookup_hash(&self) -> Option<H::Output>

Returns the hash to lookup the preimage.

If this is a Bounded::Inline, None is returned as no lookup is required.

source

pub fn len(&self) -> Option<u32>

Returns the length of the preimage or None if the length is unknown.

source

pub fn lookup_needed(&self) -> bool

Returns whether the image will require a lookup to be peeked.

source

pub fn lookup_len(&self) -> Option<u32>

The maximum length of the lookup that is needed to peek Self.

source

pub fn unrequested(hash: H::Output, len: u32) -> Self

Constructs a Lookup bounded item.

source

pub fn from_legacy_hash(hash: impl Into<H::Output>) -> Self

👎Deprecated: This API is only for transitioning to Scheduler v3 API

Constructs a Legacy bounded item.
