Struct DeveloperExtension 

pub struct DeveloperExtension {
    pub prefix: String,
    pub base_version: String,
    pub extension_level: i64,
}

A developer-defined extension to the standard the document uses (ISO 32000-1 §7.12.2, Table 50): one entry of the catalog’s /Extensions.

Fields

prefix: String

The developer’s registered prefix (Annex E), the entry’s key.

base_version: String

/BaseVersion: the PDF version the extension applies to, in the catalog /Version syntax (1.7), as written (§7.12.3).

extension_level: i64

/ExtensionLevel: the developer’s number for the extension, higher for a later extension to the same base version (§7.12.4).

Implementations

impl DeveloperExtension

pub fn base_version_numbers(&self) -> Option<(u32, u32)>

The base version as the two integers §7.12.3 reads it as, not as a real number (1.7 is (1, 7)); None when it is not two integers around a period.

Covers ISO 32000-1 §7.12.3.
