Trait Implementations

impl Check for SerializedEdge

fn add_refs<T>( &self, _txn: &T, _refs: &mut BTreeMap<u64, usize, Global> ) -> Result<(), <T as LoadPage>::Error>where T: LoadPage, <T as LoadPage>::Error: Debug,

impl Clone for SerializedEdge

fn clone(&self) -> SerializedEdge

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SerializedEdge

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

Formats the value using the given formatter.

impl Hash for SerializedEdge

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 Ord for SerializedEdge

fn cmp(&self, other: &SerializedEdge) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<SerializedEdge> for SerializedEdge

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<SerializedEdge> for SerializedEdge

fn partial_cmp(&self, other: &SerializedEdge) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Storable for SerializedEdge

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.

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 SubAssign<EdgeFlags> for SerializedEdge

fn sub_assign(&mut self, e: EdgeFlags)

Performs the -= operation.

impl UnsizedStorable for SerializedEdge

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.

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).

const ALIGN: usize = 4usize

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