Enum LayerIntent 

#[non_exhaustive]
pub enum LayerIntent {
    View,
    Design,
    Export,
    Multiple(Vec<String>),
    Other(String),
}

/Intent on an OCG, declaring which audiences the layer is for.

PDF allows a single name or an array of names; an array becomes LayerIntent::Multiple. Names other than View/Design/Export are preserved verbatim under LayerIntent::Other.

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.

View

Default. Layer is meaningful for on-screen viewing.

Design

Layer represents structural design content (CAD drawings, engineering layers, etc.). Some viewers ignore non-View intents in interactive mode.

Export

Layer is intended for export workflows (data extraction, archiving).

Multiple(Vec<String>)

Multiple intents — array form.

Other(String)

An intent name not covered by the spec’s standard set.
