Struct Sealed

pub struct Sealed<T> { /* private fields */ }

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.

Implementations

impl<T> Sealed<T>

pub fn new(inner: T) -> Self

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) -> Self

where T: Sized, F: FnOnce(&T) -> B256,

Seal the inner item with some function.

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

where T: Sized, F: FnOnce(&T) -> B256,

Seal a reference to the inner item with some function.

pub const fn new_unchecked(inner: T, seal: B256) -> Self

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

pub fn into_parts(self) -> (T, B256)

Decompose into parts.

pub fn split(self) -> (T, B256)

Decompose into parts. Alias for Self::into_parts.

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

Get the inner item.

pub const fn seal(&self) -> B256

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.

Trait Implementations

impl<'a, T> Arbitrary<'a> for Sealed<T>

where T: for<'b> Arbitrary<'b> + Sealable,

Available on crate feature arbitrary only.

fn arbitrary(u: &mut Unstructured<'a>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

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

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl<T: Arbitrary> Arbitrary for Sealed<T>

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: Self::Parameters) -> Self::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: Clone> Clone for Sealed<T>

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> Debug for Sealed<T>

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

Formats the value using the given formatter.

impl<T> Default for Sealed<T>

where T: Sealable + Default,

fn default() -> Self

Returns the “default value” for a type.

impl<T> Deref for Sealed<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

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

where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Hash> Hash for Sealed<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: PartialEq> PartialEq for Sealed<T>

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::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
