Struct PdfVersion 

pub struct PdfVersion {
    pub major: u8,
    pub minor: u8,
}

The version digits from a %PDF-M.N header.

Two independent digits, not a packed integer. The packed form — 17 for 1.7 — survives only as a private conversion beside the header parser (pdfrum-parser’s doc::read_version), and appears in no public signature anywhere in the workspace.

Ordering is lexicographic on (major, minor), so PDF_1_4 < PDF_1_7 < PDF_2_0 — which is what “at least version X” means, and what a packed comparison gets wrong the moment a major digit reaches two of its own (PdfVersion::new(11, 0) orders above 1.9; 110 > 19 only by luck of the digit count).

use pdfrum_common::PdfVersion;

assert_eq!(PdfVersion::PDF_1_7.to_string(), "1.7");
assert!(PdfVersion::PDF_1_4 < PdfVersion::PDF_2_0);
assert_eq!(PdfVersion::new(1, 5), PdfVersion::PDF_1_5);

Fields

major: u8

The digit before the dot.

minor: u8

The digit after it.

Implementations

impl PdfVersion

pub const PDF_1_0: Self

PDF 1.0, the oldest version the writer will emit on request.

pub const PDF_1_4: Self

PDF 1.4 — the last version before object and cross-reference streams.

pub const PDF_1_5: Self

PDF 1.5, which introduced cross-reference and object streams.

pub const PDF_1_7: Self

PDF 1.7, ISO 32000-1, and the writer’s fallback for a document that declares no version of its own.

pub const PDF_2_0: Self

PDF 2.0, ISO 32000-2.

pub const fn new(major: u8, minor: u8) -> Self

A version from its two digits.
