Enum SessionError 

pub enum SessionError {
    NotFound,
    Io(String),
}

Errors a SessionSource can surface.

Deliberately tiny: the dispatcher only needs to know whether a requested id was missing (for a friendly “no such session” line) vs. something else went wrong (alert the operator).

Variants

NotFound

Io(String)
