impl<'a> From<&'a Hash> for SerializedHash

fn from(s: &'a Hash) -> Self

Converts to this type from the input type.

impl<'a> From<&'a SerializedHash> for Hash

fn from(s: &'a SerializedHash) -> Hash

Converts to this type from the input type.

impl From<&SerializedHash> for Scalar

fn from(s: Hash) -> SerializedHash

Converts to this type from the input type.

impl From<SerializedHash> for Hash

fn from(s: SerializedHash) -> Hash

Converts to this type from the input type.

impl Hash for SerializedHash

fn hash<H: Hasher>(&self, hasher: &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 Ord for SerializedHash

fn cmp(&self, b: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SerializedHash

fn eq(&self, b: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for SerializedHash

fn partial_cmp(&self, b: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Storable for SerializedHash

type PageReferences = Empty<u64>

An iterator over the offsets to pages contained in this value. Only values from this crate can generate non-empty iterators, but combined values (like tuples) must chain the iterators returned by method page_offsets.

fn page_references(&self) -> Self::PageReferences

If this value is an offset to another page at offset offset, return Some(offset). Return None else.

fn compare<T>(&self, _: &T, b: &Self) -> Ordering

This is required for B trees, not necessarily for other structures. The default implementation panics.

unsafe fn drop<T>(&self, txn: &mut T) -> Result<(), <T as LoadPage>::Error>

where T: AllocPage,

If this value is an offset to another page at offset offset, return Some(offset). Return None else.

impl UnsizedStorable for SerializedHash

fn size(&self) -> usize

If Self::SIZE.is_some(), this must return the same value. The default implementation is Self;:SIZE.unwrap().

unsafe fn onpage_size(_: *const u8) -> usize

Read the size from an on-page entry.

const ALIGN: usize

unsafe fn write_to_page(&self, p: *mut u8)

Write to a page. Must not overwrite the allocated size, but this isn’t checked (which is why it’s unsafe).

unsafe fn from_raw_ptr<'a, T>(_: &T, p: *const u8) -> &'a Self

unsafe fn write_to_page_alloc<T>(&self, _: &mut T, p: *mut u8)

where T: AllocPage,

Write to a page. Must not overwrite the allocated size, but this isn’t checked (which is why it’s unsafe).
