Error type describing things that can go wrong when operating on Wasm Memories.

Variants

Region(String)

Low level error with mmap.

CouldNotGrow

The operation would cause the size of the memory to exceed the maximum or would cause an overflow leading to unindexable memory.

Fields of CouldNotGrow

current: Pages

The current size in pages.

attempted_delta: Pages

The attempted amount to grow by in pages.

InvalidMemory

The operation would cause the size of the memory size exceed the maximum.

Fields of InvalidMemory

reason: String

The reason why the provided memory is invalid.

MinimumMemoryTooLarge

Caller asked for more minimum memory than we can give them.

Fields of MinimumMemoryTooLarge

min_requested: Pages

The number of pages requested as the minimum amount of memory.

max_allowed: Pages

The maximum amount of memory we can allocate.

MaximumMemoryTooLarge

Caller asked for a maximum memory greater than we can give them.

Fields of MaximumMemoryTooLarge

max_requested: Pages

The number of pages requested as the maximum amount of memory.

max_allowed: Pages

The number of pages requested as the maximum amount of memory.

Generic(String)

A user defined error value, used for error cases not listed above.

Trait Implementations

impl Clone for MemoryError

pub fn clone(&self) -> MemoryError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryError

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

Formats the value using the given formatter.

impl Display for MemoryError

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

Formats the value using the given formatter.

impl Error for MemoryError

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl Hash for MemoryError

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl PartialEq<MemoryError> for MemoryError

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

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

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

This method tests for !=.
