#[non_exhaustive]
pub enum ContiguousMemoryError {
    NoStorageLeft,
    AlreadyUsed,
    NotContained,
    DoubleFree,
    Unshrinkable {
        required_size: usize,

}

Represents errors that can occur while using the ContiguousMemoryStorage container.

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.

NoStorageLeft

Tried to store data that does not fit into any of the remaining free memory regions.

AlreadyUsed

Attempted to occupy a memory region that is already marked as taken.

NotContained

Attempted to operate on a memory region that is not contained within the AllocationTracker.

DoubleFree

Attempted to free memory that has already been deallocated.

Unshrinkable

Fields

required_size: usize

The minimum required size to house currently stored data.

The AllocationTracker does not allow shrinking to the expected size.

Lock(LockingError)

Indicates that a mutex wasn’t lockable.

TrackerInUse

Attempted to borrow the AllocationTracker which is already in use.

Layout(LayoutError)

Tuple Fields

0: LayoutError

The underlying error that caused the Layout to be considered invalid.

Indicates that the provided Layout is invalid.

BorrowMut(RegionBorrowed)

Tried mutably borrowing already borrowed region of memory

Trait Implementations

impl Debug for ContiguousMemoryError

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

Formats the value using the given formatter.

impl Display for ContiguousMemoryError

Available on crate features std or error_in_core only.

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

Formats the value using the given formatter.

impl Error for ContiguousMemoryError

Available on crate features std or error_in_core only.

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

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.
