Enum Level 

pub enum Level {
    A1b,
    A2b,
}

Which PDF/A conformance level to check against.

An enum rather than a string or a pair of numbers, because the two levels differ in what they forbid and a caller who passes the wrong spelling of a string gets no answer at all. Only the two b (basic) levels are here; the module docs say why the a levels are absent.

Variants

A1b

PDF/A-1b, ISO 19005-1:2005. Built on PDF 1.4: no transparency at all, no optional content, no embedded files, no JPEG 2000.

A2b

PDF/A-2b, ISO 19005-2:2011. Built on PDF 1.7: transparency is allowed when a blending colour space is defined, JPEG 2000 is allowed, and embedded files are allowed if they are themselves PDF/A.

Implementations

impl Level

pub const fn name(self) -> &'static str

The level’s name as ISO 19005 spells it.

pub const fn part(self) -> u8

The pdfaid:part an XMP identification schema must carry for this level: 1 for A-1, 2 for A-2.

pub const fn forbids_transparency(self) -> bool

Whether transparency is forbidden outright.

True for A-1 only. A-2 permits transparency, so the check that walks for it is skipped rather than run-and-ignored — a check that produces findings nobody reads is how a report grows noise.

Trait Implementations

impl Clone for Level

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Eq for Level

impl Hash for Level

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl Ord for Level

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Level

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
