Enum ResizableShmAllocationError 

pub enum ResizableShmAllocationError {
    MaxReallocationsReached,
    ShmAllocationError(ShmAllocationError),
    SharedMemoryCreateError(SharedMemoryCreateError),
}

Defines all erros that can occur when calling ResizableSharedMemory::allocate()

The ResizableSharedMemory cannot be resized indefinitely. If the resize limit is hit this error will be returned. It can be mitigated by providing a better ResizableSharedMemoryBuilder::max_number_of_chunks_hint() or ResizableSharedMemoryBuilder::max_chunk_layout_hint().

Trait Implementations

impl Clone for ResizableShmAllocationError

fn clone(&self) -> ResizableShmAllocationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResizableShmAllocationError

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

Formats the value using the given formatter.

impl Display for ResizableShmAllocationError

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

Formats the value using the given formatter.

impl Error for ResizableShmAllocationError

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.

impl From<SharedMemoryCreateError> for ResizableShmAllocationError

fn from(v: SharedMemoryCreateError) -> Self

Converts to this type from the input type.

impl From<ShmAllocationError> for ResizableShmAllocationError

fn from(v: ShmAllocationError) -> Self

Converts to this type from the input type.

impl Hash for ResizableShmAllocationError

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

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 PartialEq for ResizableShmAllocationError

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