Enum CoverageSidecarError 

#[non_exhaustive]
pub enum CoverageSidecarError {
    Layout {
        source: CoverageLayoutError,
        backtrace: Backtrace,
    },
    Codec {
        source: CoverageCodecError,
    },
    EntityIdentitySchema {
        source: Box<SchemaCompatibilityError>,
    },
    Storage {
        source: StorageError,
    },
}

Errors that can occur during coverage sidecar operations.

These errors propagate from lower layers: layout validation, serialization, storage, and file I/O. Callers should inspect the variant to determine the nature of the failure and how to recover.

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.

Layout

Layout validation error (e.g., invalid coverage ID or path).

Fields

source: CoverageLayoutError

The underlying layout error.

backtrace: Backtrace

Backtrace captured at the sidecar boundary.

Codec

Coverage serialization or deserialization failed.

Fields

source: CoverageCodecError

The underlying coverage codec error.

EntityIdentitySchema

An entity identity does not match the table’s configured schema.

Fields

source: Box<SchemaCompatibilityError>

Identity arity or scalar-type mismatch.

Storage

Storage I/O error (read, write, or metadata operations).

Fields

source: StorageError

The underlying storage error.

Trait Implementations

impl Debug for CoverageSidecarError

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

Formats the value using the given formatter.

impl Display for CoverageSidecarError

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

Formats the value using the given formatter.

impl Error for CoverageSidecarError

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 CoverageSidecarError

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.
