Struct ic_cdk::api::stable::CanisterStableMemory

pub struct CanisterStableMemory {}

A standard implementation of StableMemory.

Useful for creating StableWriter and StableReader.

Trait Implementations

impl Clone for CanisterStableMemory

fn clone(&self) -> CanisterStableMemory

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CanisterStableMemory

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

impl Default for CanisterStableMemory

fn default() -> CanisterStableMemory

Returns the “default value” for a type.

impl StableMemory for CanisterStableMemory

fn stable_size(&self) -> u32

Gets current size of the stable memory (in WASM pages).

fn stable64_size(&self) -> u64

Similar to stable_size but with support for 64-bit addressed memory.

fn stable_grow(&self, new_pages: u32) -> Result<u32, StableMemoryError>

Attempts to grow the stable memory by new_pages (added pages).

fn stable64_grow(&self, new_pages: u64) -> Result<u64, StableMemoryError>

Similar to stable_grow but with support for 64-bit addressed memory.

fn stable_write(&self, offset: u32, buf: &[u8])

Writes data to the stable memory location specified by an offset.

fn stable64_write(&self, offset: u64, buf: &[u8])

Similar to stable_write but with support for 64-bit addressed memory.

fn stable_read(&self, offset: u32, buf: &mut [u8])

Reads data from the stable memory location specified by an offset.

fn stable64_read(&self, offset: u64, buf: &mut [u8])

Similar to stable_read but with support for 64-bit addressed memory.
