Errors from the global and entity-aware coverage codecs.

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.

BitmapSerialization

I/O error during serialization of a coverage bitmap.

Fields

source: Error

The underlying I/O error.

backtrace: Backtrace

Backtrace captured at the codec boundary.

BitmapDeserialization

I/O error during deserialization of a coverage bitmap.

Fields

source: Error

The underlying I/O error.

backtrace: Backtrace

Backtrace captured at the codec boundary.

LengthOverflow

An in-memory length cannot be represented by the format.

Fields

field: &'static str

The field whose length overflowed.

backtrace: Backtrace

Backtrace captured at the codec boundary.

InvalidEntityCoverageMagic

The payload is not entity-aware coverage.

Fields

backtrace: Backtrace

Backtrace captured at the codec boundary.

TruncatedPayload

A fixed-size field is incomplete.

Fields

backtrace: Backtrace

Backtrace captured at the codec boundary.

InvalidLength

A declared count or length is not valid for the remaining payload.

Fields

field: &'static str

The invalid field.

backtrace: Backtrace

Backtrace captured at the codec boundary.

InvalidEntityUtf8

An identity component is not valid UTF-8.

Fields

source: Utf8Error

The UTF-8 validation error.

backtrace: Backtrace

Backtrace captured at the codec boundary.

UnknownEntityValueTag

An identity component uses an unknown scalar type tag.

Fields

tag: u8

Unrecognized encoded type tag.

backtrace: Backtrace

Backtrace captured at the codec boundary.

InvalidEntityIdentity

An encoded identity is incomplete.

Fields

source: EntityIdentityError

The identity validation error.

backtrace: Backtrace

Backtrace captured at the codec boundary.

DuplicateEntityIdentity

The payload contains the same identity more than once.

Fields

identity: EntityIdentity

The repeated identity.

backtrace: Backtrace

Backtrace captured at the codec boundary.

MalformedNestedCoverage

A nested RoaringTreemap payload is malformed.

Fields

source: Box<CoverageCodecError>

The nested global coverage error.

TrailingBytes

Bytes remain after the declared coverage payload.

Fields

backtrace: Backtrace

Backtrace captured at the codec boundary.

Trait Implementations

impl Debug for CoverageCodecError

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

Formats the value using the given formatter.

impl Display for CoverageCodecError

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

Formats the value using the given formatter.

impl Error for CoverageCodecError

where Self: Debug + Display,

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 ErrorCompat for CoverageCodecError

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

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl From<CoverageCodecError> for CoverageSidecarError

where CoverageCodecError: Into<CoverageCodecError>,

fn from(error: CoverageCodecError) -> Self

Converts to this type from the input type.
