Implementations

impl RedisError

pub fn parse_redirect(msg: &str) -> Option<Self>

Parse a Redis error message to check for MOVED or ASK redirects

pub const fn is_redirect(&self) -> bool

Check if this error is a redirect (MOVED or ASK)

pub fn redirect_target(&self) -> Option<(String, u16)>

Get the target address from a redirect error

pub const fn redirect_slot(&self) -> Option<u16>

Get the slot number from a redirect error

Trait Implementations

impl Debug for RedisError

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

Formats the value using the given formatter.

impl Display for RedisError

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

Formats the value using the given formatter.

impl Error for RedisError

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 RedisError

fn from(source: Error) -> Self

Converts to this type from the input type.
