Struct Sealed

pub struct Sealed<T> {
    inner: T,
    seal: FixedBytes<32>,
}

A consensus hashable item, with its memoized hash.

We do not implement any specific hashing algorithm here. Instead types implement the Sealable trait to provide define their own hash.

Fields

inner: T

seal: FixedBytes<32>

Implementations

impl<T> Sealed<T>

pub fn new(inner: T) -> Sealed<T>

where T: Sealable,

Seal the inner item.

pub fn new_ref(inner: &T) -> Sealed<&T>

where T: Sealable,

Seal the inner item, by reference.

pub fn new_with<F>(inner: T, f: F) -> Sealed<T>

where F: FnOnce(&T) -> FixedBytes<32>,

Seal the inner item with some function.

pub fn new_ref_with<F>(inner: &T, f: F) -> Sealed<&T>

where F: FnOnce(&T) -> FixedBytes<32>,

Seal a reference to the inner item with some function.

pub const fn new_unchecked(inner: T, seal: FixedBytes<32>) -> Sealed<T>

Instantiate without performing the hash. This should be used carefully.

pub fn into_parts(self) -> (T, FixedBytes<32>)

Decompose into parts.

pub fn split(self) -> (T, FixedBytes<32>)

Decompose into parts. Alias for Self::into_parts.

pub const fn inner(&self) -> &T

Get the inner item.

pub const fn seal(&self) -> FixedBytes<32>

Get the hash.

pub const fn hash(&self) -> FixedBytes<32>

Get the hash.

pub fn into_inner(self) -> T

Unseal the inner item, discarding the hash.

pub fn unseal(self) -> T

Unseal the inner item, discarding the hash. Alias for Self::into_inner.

fn size_hint(depth: usize) -> (usize, Option<usize>)

impl<T> Arbitrary for Sealed<T>

where T: Arbitrary,

type Parameters = (<T as Arbitrary>::Parameters, <FixedBytes<32> as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<T as Arbitrary>::Strategy, <FixedBytes<32> as Arbitrary>::Strategy), fn(_: (T, FixedBytes<32>)) -> Sealed<T>>

The type of Strategy used to generate values of type Self.

fn arbitrary_with( _top: <Sealed<T> as Arbitrary>::Parameters, ) -> <Sealed<T> as Arbitrary>::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl<T> AsRef<T> for Sealed<T>

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<T> Clone for Sealed<T>

where T: Clone,

fn clone(&self) -> Sealed<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Sealed<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for Sealed<T>

where T: Sealable + Default,

fn default() -> Sealed<T>

Returns the “default value” for a type.

impl<T> Deref for Sealed<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &<Sealed<T> as Deref>::Target

Dereferences the value.

impl<'de, T> Deserialize<'de> for Sealed<T>

where T: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<Sealed<T>, <__D as Deserializer<'de>>::Error>

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T> PartialEq for Sealed<T>

where T: PartialEq,

fn eq(&self, other: &Sealed<T>) -> 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<T> Serialize for Sealed<T>

where T: Serialize,

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where T: Copy,

impl<T> Eq for Sealed<T>

where T: Eq,

impl<T> StructuralPartialEq for Sealed<T>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
