Implementations

impl Error

pub fn corrupted(message: impl Into<String>) -> Error

Create a corrupted data error.

pub fn corrupted_at(message: impl Into<String>, offset: usize) -> Error

Create a corrupted data error with offset context.

pub fn buffer_too_small(required: usize, provided: usize) -> Error

Create a buffer too small error.

pub fn checksum_mismatch(expected: u32, actual: u32) -> Error

Create a checksum mismatch error.

pub fn unexpected_eof(bytes_read: usize) -> Error

Create an unexpected EOF error.

pub fn io(message: impl Into<String>) -> Error

Create an I/O error with a custom message.

pub fn algorithm(algorithm: &'static str, message: impl Into<String>) -> Error

Create an algorithm-specific error.

pub fn is_recoverable(&self) -> bool

Check if error is recoverable (can retry with different parameters).

pub fn category(&self) -> &'static str

Get error category for metrics.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Error

Converts to this type from the input type.
