Enum SessionControlError 

pub enum SessionControlError {
    Unsupported(String),
    Invalid(String),
    Failed(String),
}

Why a mutation could not be performed.

Variants

Unsupported(String)

The harness has no door for what was asked (refused, never faked).

Invalid(String)

The request itself is incoherent.

Failed(String)

The harness’s door ran and failed; the message carries its own error.

impl Eq for SessionControlError

impl Error for SessionControlError

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
