Struct ink_storage::traits::KeyPtr

pub struct KeyPtr { /* private fields */ }

A key pointer.

This wraps a base key and provides an interface to mimic pointer arithmetic. Mainly used to coordinate keys through static storage structures.

Implementations

impl KeyPtr

pub fn advance_by(&mut self, new_shift: u64) -> &Key

Advances the key pointer by the given amount and returns the old value.

pub fn key(&self) -> &Key

Returns the underlying offset key.

Trait Implementations

impl Clone for KeyPtr

fn clone(&self) -> KeyPtr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyPtr

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

Formats the value using the given formatter.

impl ExtKeyPtr for KeyPtr

fn next_for<T>(&mut self) -> &Keywhere
    T: SpreadLayout,

Advances the key pointer by the same amount of the footprint of the generic type parameter of T and returns the old value.

impl From<Key> for KeyPtr

fn from(key: Key) -> KeyPtr

Converts to this type from the input type.

impl PartialEq<KeyPtr> for KeyPtr

fn eq(&self, other: &KeyPtr) -> bool

This method tests for self and other values to be equal, and is used by ==.

const 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.
