Struct redis::RedisError

pub struct RedisError { /* fields omitted */ }

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

Methods

impl RedisError

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 is_connection_refusal(&self) -> bool

Returns true if this error indicates that the connection was refused. You should generally not rely much on this function unless you are writing unit tests that want to detect if a local server is available.

pub fn is_timeout(&self) -> bool

Returns true if error was caused by I/O time out. Note that this may not be accurate depending on platform.

pub fn is_connection_dropped(&self) -> bool

Returns true if error was caused by a dropped connection.

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

Returns the extension error code
