Enum frame_support::traits::Bounded
source · pub enum Bounded<T> {
Legacy {
hash: Hash,
dummy: PhantomData<T>,
},
Inline(BoundedInline),
Lookup {
hash: Hash,
len: u32,
},
}
Variants§
Legacy
A Blake2 256 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.
Inline(BoundedInline)
A an bounded Call
. Its encoding must be at most 128 bytes.
Lookup
A Blake2-256 hash of the call together with an upper limit for its size.
Implementations§
source§impl<T> Bounded<T>
impl<T> Bounded<T>
sourcepub fn transmute<S: Encode>(self) -> Bounded<S>where
T: Encode + EncodeLike<S>,
pub fn transmute<S: Encode>(self) -> Bounded<S>where T: Encode + EncodeLike<S>,
Casts the wrapped type into something that encodes alike.
Examples
use frame_support::traits::Bounded;
// Transmute from `String` to `&str`.
let x: Bounded<String> = Bounded::Inline(Default::default());
let _: Bounded<&str> = x.transmute();
sourcepub fn hash(&self) -> Hash
pub fn hash(&self) -> Hash
Returns the hash of the preimage.
The hash is re-calculated every time if the preimage is inlined.
sourcepub fn lookup_hash(&self) -> Option<Hash>
pub fn lookup_hash(&self) -> Option<Hash>
Returns the hash to lookup the preimage.
If this is a Bounded::Inline
, None
is returned as no lookup is required.
sourcepub fn len(&self) -> Option<u32>
pub fn len(&self) -> Option<u32>
Returns the length of the preimage or None
if the length is unknown.
sourcepub fn lookup_needed(&self) -> bool
pub fn lookup_needed(&self) -> bool
Returns whether the image will require a lookup to be peeked.
sourcepub fn lookup_len(&self) -> Option<u32>
pub fn lookup_len(&self) -> Option<u32>
The maximum length of the lookup that is needed to peek Self
.
sourcepub fn unrequested(hash: Hash, len: u32) -> Self
pub fn unrequested(hash: Hash, len: u32) -> Self
Constructs a Lookup
bounded item.
sourcepub fn from_legacy_hash(hash: impl Into<Hash>) -> Self
👎Deprecated: This API is only for transitioning to Scheduler v3 API
pub fn from_legacy_hash(hash: impl Into<Hash>) -> Self
Constructs a Legacy
bounded item.
