An error encountered while setting up or manipulating a shared memory region

Variants

Bounds(usize, usize, usize)

Some operation on the shared memory attempted to read or write out of bounds

FileMetadata(Error)

When creating a memory with contents from a file, metadata for that file could not be read

FileTooLarge(TryFromIntError)

When creating a memory with contents from a file, that file was logically larger than the range of a usize.

LockError(String, Backtrace)

The locking discipline used to enforce temporary exclusive access by the host to a shared memory failed in some way

MemoryAllocationFailed(Option<i32>)

A request to allocate a shared memory could not be fulfilled by the host operating system

MemoryRequest(usize, usize, usize, usize)

A ruqest to allocate a shared shared memory had an invalid size, due either to bounds or alignment.

MmapFailed(Option<i32>)

An request to mmap a file or create an anonymous memory could not be fulfilled by the host operating system

MprotectFailed(Option<i32>)

A request to change the host-side permissions on the guard pages of a shared memory region could not be fulfilled by the host operating system

ReadonlySharedMemoryExclusiveRequest

Calling code attempted to take exclusive (write) access to a ReadonlySharedMemory.

Stack(StackError)

The stack discipline of guest I/O was violated in some way

TryFromSlice(TryFromSliceError)

An error was encountered when trying to convert a slice of raw bytes into some logical data

TryFromInt(TryFromIntError)

An error was encountered during a routine error conversion that should have been infallible

Trait Implementations

impl Debug for SharedMemoryError

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

Formats the value using the given formatter.

impl Display for SharedMemoryError

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

Formats the value using the given formatter.

impl Error for SharedMemoryError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.
