Struct sanakirja_core::btree::Db_

pub struct Db_<K: ?Sized, V: ?Sized, P: BTreePage<K, V>> {
    pub db: NonZeroU64,
    pub k: PhantomData<K>,
    pub v: PhantomData<V>,
    pub p: PhantomData<P>,
}

A database, which is essentially just a page offset along with markers.

Fields

db: NonZeroU64

k: PhantomData<K>

v: PhantomData<V>

p: PhantomData<P>

Implementations

impl<K: ?Sized, V: ?Sized, P: BTreePage<K, V>> Db_<K, V, P>

pub unsafe fn from_page(db: u64) -> Self

Load a database from a page offset.

Trait Implementations

impl<K: Debug + ?Sized, V: Debug + ?Sized, P: Debug + BTreePage<K, V>> Debug for Db_<K, V, P>

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

Formats the value using the given formatter.

impl<K: Storable, V: Storable, P: BTreePage<K, V> + Debug> Storable for Db_<K, V, P>

type PageReferences = Once<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.

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

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

fn compare<T: LoadPage>(&self, _txn: &T, _b: &Self) -> Ordering

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