pub struct MemoryStorage { /* private fields */ }

Implementations

source

impl MemoryStorage

source

pub fn new() -> MemoryStorage

Trait Implementations

source

impl Default for MemoryStorage

source

fn default() -> MemoryStorage

Returns the “default value” for a type. Read more

source

impl ReadonlyStorage for MemoryStorage

source

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

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

source

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

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

source

impl Storage for MemoryStorage

source

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

source

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

Removes a database entry at key. Read more

impl<T> Borrow<T> for T where
T: ?Sized,

const: unstable · source

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

source

impl<T> BorrowMut<T> for T where
T: ?Sized,

const: unstable · source

fn borrow_mut(&mut self) -> &mut T

source

impl<T> From<T> for T

const: unstable · source

fn from(t: T) -> T

Returns the argument unchanged.

source

impl<T, U> Into for T where
U: From<T>,

const: unstable · source

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

source

impl<T> Same<T> for T

type Output = T

Should always be Self

source

impl<T, U> TryFrom for T where
U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

const: unstable · source

fn try_from(value: U) -> Result<T, <T as TryFrom>::Error>

Performs the conversion.

source

impl<T, U> TryInto for T where
U: TryFrom<T>,

type Error = >::Error

The type returned in the event of a conversion error.

const: unstable · source

fn try_into(self) -> Result<U, >::Error>

Performs the conversion.
