Implementations

impl SierraError

pub fn from_redis_error(redis_error: RedisError) -> Self

Parse a Redis error response into a SierraError.

pub fn is_retryable(&self) -> bool

Check if this error indicates a temporary failure that should be retried.

pub fn is_cluster_issue(&self) -> bool

Check if this error indicates a cluster availability issue.

pub fn is_client_error(&self) -> bool

Check if this error indicates a client argument error.

pub fn error_code(&self) -> Option<ErrorCode>

Get the error code if this is a protocol error.

pub fn retry_delay_ms(&self) -> Option<u64>

Get a suggested retry delay in milliseconds for retryable errors. Returns None if the error should not be retried.

Trait Implementations

impl Debug for SierraError

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

Formats the value using the given formatter.

impl Display for SierraError

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

Formats the value using the given formatter.

impl Error for SierraError

fn source(&self) -> Option<&(dyn Error + 'static)>

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<RedisError> for SierraError

fn from(err: RedisError) -> Self

Converts to this type from the input type.
