Struct sc_client_api::backend::KeyValueStates

pub struct KeyValueStates(pub Vec<KeyValueStorageLevel>);

Multiple key value state. States are ordered by root storage key.

Tuple Fields

0: Vec<KeyValueStorageLevel>

Implementations

impl KeyValueStates

pub fn len(&self) -> usize

Return total number of key values in states.

pub fn update_last_key( &self, stopped_at: usize, last: &mut SmallVec<[Vec<u8>; 2]>, ) -> bool

Update last keys accessed from this state.

Trait Implementations

impl Clone for KeyValueStates

fn clone(&self) -> KeyValueStates

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> From<I> for KeyValueStates

where I: IntoIterator<Item = (Vec<u8>, (Vec<(Vec<u8>, Vec<u8>)>, Vec<Vec<u8>>))>,

fn from(b: I) -> KeyValueStates

Converts to this type from the input type.

impl PartialEq for KeyValueStates

fn eq(&self, other: &KeyValueStates) -> 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.
