where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for L64

fn cmp(&self, x: &L64) -> 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 L64

fn eq(&self, other: &L64) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for L64

fn partial_cmp(&self, x: &L64) -> 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 Serialize for L64

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Storable for L64

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) -> <L64 as Storable>::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: &L64) -> 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 StructuralPartialEq for L64

impl SubAssign<usize> for L64

fn sub_assign(&mut self, x: usize)

Performs the -= operation.

impl UnsizedStorable for L64

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 L64

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).
