pub fn new() -> Self

Trait Implementations

impl Debug for MockStorage

This debug implementation is made for inspecting storages in unit testing. It is made for human readability only and the output can change at any time.

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

Formats the value using the given formatter.

impl Default for MockStorage

fn default() -> MockStorage

Returns the “default value” for a type.

impl Storage for MockStorage

fn range<'a>( &'a self, start: Option<&[u8]>, end: Option<&[u8]>, order: Order, ) -> Box<dyn Iterator<Item = Record> + 'a>

range allows iteration over a set of keys, either forwards or backwards uses standard rust range notation, and eg db.range(b“foo“..b“bar“) also works reverse

fn get(&self, key: &[u8]) -> Option<Vec<u8>>

Returns None when key does not exist. Returns Some(Vec) when key exists.

fn set(&mut self, key: &[u8], value: &[u8])

fn remove(&mut self, key: &[u8])

Removes a database entry at key.

fn range_keys<'a>( &'a self, start: Option<&[u8]>, end: Option<&[u8]>, order: Order, ) -> Box<dyn Iterator<Item = Vec<u8>> + 'a>

Allows iteration over a set of keys, either forwards or backwards.

fn range_values<'a>( &'a self, start: Option<&[u8]>, end: Option<&[u8]>, order: Order, ) -> Box<dyn Iterator<Item = Vec<u8>> + 'a>

Allows iteration over a set of values, either forwards or backwards.
