Struct PdfPermissions 

pub struct PdfPermissions<'a> { /* private fields */ }

The collection of document permissions and security handler settings for a single PdfDocument.

Note that Pdfium currently only offers support for reading the existing permissions of a document. It does not support changing existing permissions or adding new permissions to a document.
