Struct RpError

pub struct RpError { /* private fields */ }

Represents a redis error. For the most part you should be using the Error trait to interact with this rather than the actual struct.

Implementations

impl RpError

Indicates a general failure in the library.

pub fn kind(&self) -> ErrorKind

Returns the kind of the error.

pub fn category(&self) -> &str

Returns the name of the error category for display purposes.

pub fn is_io_error(&self) -> bool

Indicates that this failure is an IO failure.

pub fn extension_error_code(&self) -> Option<&str>

Returns the extension error code

pub fn extension_error_detail(&self) -> Option<&str>

Returns the extension error detail

Trait Implementations

impl Debug for RpError

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

Formats the value using the given formatter.

impl Display for RpError

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

Formats the value using the given formatter.

impl Error for RpError

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

Returns the lower-level source of this error, if any.

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<(ErrorKind, &'static str)> for RpError

fn from((kind, desc): (ErrorKind, &'static str)) -> RpError

Converts to this type from the input type.

impl From<(ErrorKind, &'static str, String)> for RpError

fn from((kind, desc, detail): (ErrorKind, &'static str, String)) -> RpError

Converts to this type from the input type.

impl From<Error> for RpError

fn from(err: Error) -> RpError

Converts to this type from the input type.

impl PartialEq for RpError

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