Enum CacheError 

pub enum CacheError {
    InvalidMagic([u8; 4]),
    UnsupportedVersion(u8),
    DataCorrupted(String),
    UnexpectedEof,
    EventDataError(String),
    ColumnCountMismatch {
        expected: usize,
        actual: usize,
    },
}

Errors returned by cache encoding and decoding.

Variants

InvalidMagic([u8; 4])

The file does not start with BNCH.

UnsupportedVersion(u8)

The format version is newer than this library supports.

DataCorrupted(String)

CRC-64 mismatch — data is corrupted or truncated.

UnexpectedEof

Unexpected end of data while reading a column or header.

EventDataError(String)

JSON serialisation / deserialisation of event data failed.

ColumnCountMismatch

Column count mismatch between header and data.

Fields

expected: usize

actual: usize

Trait Implementations

impl Clone for CacheError

fn clone(&self) -> CacheError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheError

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

Formats the value using the given formatter.

impl Display for CacheError

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

Formats the value using the given formatter.

impl Error for CacheError

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<CacheError> for CacheReaderError

fn from(source: CacheError) -> Self

Converts to this type from the input type.

impl From<Error> for CacheError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl PartialEq for CacheError

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