Enum PageEncoding

Source

pub enum PageEncoding {
    Legacy(ArrayEncoding),
    Structural(PageLayout),
}

Expand description

Top-level encoding message for a page. Wraps both the v2.0 pb::ArrayEncoding grammar and the structural pb21::PageLayout grammar.

A file should only use one or the other and never both. 2.0 decoders can always assume this is pb::ArrayEncoding and 2.1+ decoders can always assume this is pb::PageLayout
