Enum gcore::errors::MemoryError

#[non_exhaustive]
pub enum MemoryError {
    RuntimeAllocOutOfBounds,
    AccessOutOfBounds,
}

Memory error.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RuntimeAllocOutOfBounds

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

AccessOutOfBounds

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

Trait Implementations

impl Clone for MemoryError

fn clone(&self) -> MemoryError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryError

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

Formats the value using the given formatter.

impl Display for MemoryError

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

Formats the value using the given formatter.

impl From<MemoryError> for ExtError

fn from(original: MemoryError) -> ExtError

Converts to this type from the input type.

impl Hash for MemoryError

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for MemoryError

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<MemoryError> for MemoryError

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

impl PartialOrd<MemoryError> for MemoryError

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Sequence for MemoryError

const CARDINALITY: usize = 2usize

Number of values of type Self.

fn next(&self) -> Option<MemoryError>

Returns value following *self or None if this was the end.

fn previous(&self) -> Option<MemoryError>

Returns value preceding *self or None if this was the beginning.

fn first() -> Option<MemoryError>

Returns the first value of type Self.

fn last() -> Option<MemoryError>

Returns the last value of type Self.
