Enum ReadOptionsError 

pub enum ReadOptionsError {
    NotARevision(NotARevision),
    EmptyRange(EmptyRange),
}

Why the options of a read are refused (see check_read_options).

Variants

NotARevision(NotARevision)

An ID of a bound is not the ID of an event.

EmptyRange(EmptyRange)

The bounds leave no room for an event.
