Enum ReaderKey 

#[non_exhaustive]
pub enum ReaderKey<'a> {
    Value(&'a str),
    Position(usize),
}

A key to access content within a Reader.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Value(&'a str)

A string value, intended for lookup within a Reader.

For an Epub, this value corresponds to the idref of a spine entry.

Position(usize)

An absolute position within the internal buffer of a Reader.

When passed as an argument to a reader, it must be less than Reader::len or ReaderError::OutOfBounds will be returned.
