Implementations

impl Error

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

Returns a stable error code for this error variant. These codes are stable and can be used by clients for error classification.

pub fn is_retryable(&self) -> bool

Returns true if this error is potentially retryable.

Transient errors like IO errors are retryable, while logical errors like InvalidArgument or ConditionalCheckFailed are not.

pub fn with_context(self, context: &str) -> Error

Adds context to an error by wrapping it in an Internal error.

This is useful for adding operation context to errors that propagate from lower layers.

Examples

use kstone_core::Error;

fn write_data() -> Result<(), Error> {
    // Some operation that might fail
    Err(Error::Io(std::io::Error::new(
        std::io::ErrorKind::NotFound,
        "file not found"
    )))
}

fn save_record() -> Result<(), Error> {
    write_data().map_err(|e| e.with_context("failed to save record"))
}

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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) -> Self

Converts to this type from the input type.
