Errors that can occur when checking archive memory.

Variants

Overflow

Fields

base: *const u8

The base pointer

offset: isize

The offset

Computing the target of a relative pointer overflowed

Underaligned

Fields

expected_align: usize

The expected alignment of the archive

actual_align: usize

The actual alignment of the archive

The archive is under-aligned for one of the types inside

OutOfBounds

Fields

base: *const u8

The base of the relative pointer

offset: isize

The offset of the relative pointer

range: Range<*const u8>

The pointer range of the archive

A pointer pointed outside the bounds of the archive

Overrun

Fields

ptr: *const u8

The pointer to the type

size: usize

The desired size of the type

range: Range<*const u8>

The pointer range of the archive

There wasn’t enough space for the desired type at the pointed location

Unaligned

Fields

ptr: *const u8

The pointer to the type

align: usize

The required alignment of the type

The pointer wasn’t aligned properly for the desired type

SubtreePointerOutOfBounds

Fields

ptr: *const u8

The pointer to the subtree

subtree_range: Range<*const u8>

The subtree range

The pointer wasn’t within the subtree range

SubtreePointerOverrun

Fields

ptr: *const u8

The pointer to the subtree type,

size: usize

The desired size of the type

subtree_range: Range<*const u8>

The subtree range

There wasn’t enough space in the subtree range for the desired type at the pointed location

RangePoppedOutOfOrder

Fields

expected_depth: usize

The expected depth of the range

actual_depth: usize

The actual depth of the range

A subtree range was popped out of order.

Subtree ranges must be popped in the reverse of the order they are pushed.

UnpoppedSubtreeRanges

Fields

last_range: usize

The depth of the last subtree that was pushed

A subtree range was not popped before validation concluded.

ExceededMaximumSubtreeDepth

Fields

max_subtree_depth: usize

The maximum depth that subtrees may be validated down to

The maximum subtree depth was reached or exceeded.

LayoutError

Fields

layout_error: LayoutError

A layout error

A layout error occurred

Trait Implementations

impl Debug for ArchiveError

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

Formats the value using the given formatter.

impl Display for ArchiveError

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

Formats the value using the given formatter.

impl Error for ArchiveError

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.
