Type Alias BoundedCallOf

pub type BoundedCallOf<T> = Bounded<CallOf<T>, <T as Config>::Hashing>;

Aliased Type

enum BoundedCallOf<T> {
    Legacy {
        hash: <<T as Config>::Hashing as Hash>::Output,
        dummy: PhantomData<<T as Config>::RuntimeCall>,
    },
    Inline(BoundedVec<u8, ConstU32<128>>),
    Lookup {
        hash: <<T as Config>::Hashing as Hash>::Output,
        len: u32,
    },
}

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: <<T as Config>::Hashing as Hash>::Output

dummy: PhantomData<<T as Config>::RuntimeCall>

Inline(BoundedVec<u8, ConstU32<128>>)

A 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: <<T as Config>::Hashing as Hash>::Output

len: u32

Implementations

impl<T, H> Bounded<T, H>

where H: Hash,

pub fn transmute<S>(self) -> Bounded<S, H>

where S: Encode, 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();

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

Returns the hash of the preimage.

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

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

Returns the hash to lookup the preimage.

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

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

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

pub fn lookup_needed(&self) -> bool

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

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

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

pub fn unrequested(hash: <H as Hash>::Output, len: u32) -> Bounded<T, H>

Constructs a Lookup bounded item.

pub fn from_legacy_hash(hash: impl Into<<H as Hash>::Output>) -> Bounded<T, H>

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

Constructs a Legacy bounded item.
