Struct rkv::store::multi::MultiStore

pub struct MultiStore<D> { /* private fields */ }

Implementations

impl<D> MultiStore<D>where
    D: BackendDatabase,

pub fn get<'r, R, I, C, K>(
    &self,
    reader: &'r R,
    k: K
) -> Result<Iter<'r, I>, StoreError>where
    R: Readable<'r, Database = D, RoCursor = C>,
    I: BackendIter<'r>,
    C: BackendRoCursor<'r, Iter = I>,
    K: AsRef<[u8]> + 'r,

Provides a cursor to all of the values for the duplicate entries that match this key

pub fn get_first<'r, R, K>(
    &self,
    reader: &'r R,
    k: K
) -> Result<Option<Value<'r>>, StoreError>where
    R: Readable<'r, Database = D>,
    K: AsRef<[u8]>,

Provides the first value that matches this key

pub fn put<T, K>(
    &self,
    writer: &mut Writer<T>,
    k: K,
    v: &Value<'_>
) -> Result<(), StoreError>where
    T: BackendRwTransaction<Database = D>,
    K: AsRef<[u8]>,

Insert a value at the specified key. This put will allow duplicate entries. If you wish to have duplicate entries rejected, use the put_with_flags function and specify NO_DUP_DATA

pub fn put_with_flags<T, K>(
    &self,
    writer: &mut Writer<T>,
    k: K,
    v: &Value<'_>,
    flags: T::Flags
) -> Result<(), StoreError>where
    T: BackendRwTransaction<Database = D>,
    K: AsRef<[u8]>,

pub fn delete_all<T, K>(
    &self,
    writer: &mut Writer<T>,
    k: K
) -> Result<(), StoreError>where
    T: BackendRwTransaction<Database = D>,
    K: AsRef<[u8]>,

pub fn delete<T, K>(
    &self,
    writer: &mut Writer<T>,
    k: K,
    v: &Value<'_>
) -> Result<(), StoreError>where
    T: BackendRwTransaction<Database = D>,
    K: AsRef<[u8]>,

pub fn clear<T>(&self, writer: &mut Writer<T>) -> Result<(), StoreError>where
    T: BackendRwTransaction<Database = D>,

Trait Implementations

impl<D: Clone> Clone for MultiStore<D>

fn clone(&self) -> MultiStore<D>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<D: Debug> Debug for MultiStore<D>

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

Formats the value using the given formatter.

impl<D: PartialEq> PartialEq<MultiStore<D>> for MultiStore<D>

fn eq(&self, other: &MultiStore<D>) -> 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.
