Enum UnrecoverableMemoryError

pub enum UnrecoverableMemoryError {
    AccessOutOfBounds,
    RuntimeAllocOutOfBounds,
}

Memory error in infallible sys-call.

Variants

AccessOutOfBounds

The error occurs in attempt to access memory outside wasm program memory.

RuntimeAllocOutOfBounds

The error occurs, when program tries to allocate in block-chain runtime more memory than allowed.

Trait Implementations

impl Clone for UnrecoverableMemoryError

fn clone(&self) -> UnrecoverableMemoryError

Returns a duplicate of the value.

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

impl Decode for UnrecoverableMemoryError

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Display for UnrecoverableMemoryError

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

Formats the value using the given formatter.

impl Encode for UnrecoverableMemoryError

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<UnrecoverableMemoryError> for UnrecoverableExtError

fn from(original: UnrecoverableMemoryError) -> UnrecoverableExtError

Converts to this type from the input type.

impl Ord for UnrecoverableMemoryError

fn cmp(&self, other: &UnrecoverableMemoryError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for UnrecoverableMemoryError

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for UnrecoverableMemoryError

fn partial_cmp(&self, other: &UnrecoverableMemoryError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
