OutOfBounds

Error when attempting to access stable memory out of bounds.

SegmentationFault

Error when attempting to write out of the allocated page.

Fields

page: Page

offset: PageOffset

data_size: MSize

page_size: u64

StableMemoryError(String)

Error when failing to grow stable memory.

Trait Implementations

impl CandidType for MemoryError

fn _ty() -> Type

fn id() -> TypeId

fn idl_serialize<__S>(&self, __serializer: __S) -> Result<(), __S::Error>

where __S: Serializer,

fn ty() -> Type

impl Debug for MemoryError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MemoryError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MemoryError

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

impl Error for MemoryError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
