Struct Span 

pub struct Span {
    pub start: u64,
    pub end: u64,
    pub line: Option<u32>,
    pub page: Option<u32>,
}

Where an event came from in the source.

Without this there is no --page, no jumping from a search hit, and no navigable table of contents; adding it later would mean touching every reader, so it is here from day one.

Fields

start: u64

Byte range within the original source.

end: u64

line: Option<u32>

1-based line, for formats that have lines.

page: Option<u32>

1-based page, for formats that have pages (PDF, EPUB).
