Trait DbMap

pub trait DbMap<KT: DbMapKeyType>: DbXxx<KT> {
    // Required methods
    fn iter(&self) -> DbXxxIter<KT> ;
    fn iter_mut(&mut self) -> DbXxxIterMut<KT> ;
    fn keys(&self) -> DbXxxKeys<KT> ;
    fn values(&self) -> DbXxxValues<KT> ;
}

key-value db map store interface.

Required Methods

fn iter(&self) -> DbXxxIter<KT>

An iterator visiting all key-value pairs in arbitrary order. The iterator element type is (&’a K, &’a V).

fn iter_mut(&mut self) -> DbXxxIterMut<KT>

An iterator visiting all key-value pairs in arbitrary order, with mutable references to the values. The iterator element type is (&’a K, &’a mut V).

fn keys(&self) -> DbXxxKeys<KT>

An iterator visiting all keys in arbitrary order. The iterator element type is KT.

fn values(&self) -> DbXxxValues<KT>

An iterator visiting all values in arbitrary order. The iterator element type is Vec.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
