Trait Implementations

impl<'a> Debug for Slice<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a [u8]> for Slice<'a>

fn from(m: &'a [u8]) -> Slice<'a>

Converts to this type from the input type.

impl<'a> Storable for Slice<'a>

type PageReferences = Pages

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: LoadPage>(&self, t: &T, b: &Self) -> Ordering

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

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

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

impl<'b> UnsizedStorable for Slice<'b>

const ALIGN: usize = 8usize

fn size(&self) -> usize

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

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

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

Read the size from an on-page entry. If Self::SIZE.is_some() this must be the same value.

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

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