Enum CidSet 

#[repr(u8)]
pub enum CidSet {
    Unknown = 0,
    Gb1 = 1,
    Cns1 = 2,
    Japan1 = 3,
    Korea1 = 4,
    Unicode = 5,
}

The character collection a CID belongs to — the /Registry–/Ordering pair of a /CIDSystemInfo (ISO 32000-1 §9.7.3), reduced to the five collections that have built-in tables plus “none of them”.

The discriminants index the static blob’s registry directory, so they are part of the format, not an implementation detail.

use pdfrum_cmap::{CidSet, charset_from_ordering};

assert_eq!(charset_from_ordering(b"Japan1"), CidSet::Japan1);
assert_eq!(charset_from_ordering(b"Latin1"), CidSet::Unknown);

Variants

Unknown = 0

No recognised collection: the CMap has no CID table and no CID→Unicode table.

Gb1 = 1

Adobe-GB1 — Simplified Chinese.

Cns1 = 2

Adobe-CNS1 — Traditional Chinese.

Japan1 = 3

Adobe-Japan1 — Japanese.

Korea1 = 4

Adobe-Korea1 — Korean.

Unicode = 5

Adobe-Identity / UCS: the CID is the Unicode scalar value.

Implementations

impl CidSet

pub fn ordinal(self) -> u8

The registry’s ordinal, as the blob and the /Ordering table use it.

Trait Implementations

impl Clone for CidSet

fn clone(&self) -> CidSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CidSet

impl Debug for CidSet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CidSet

fn default() -> CidSet

Returns the “default value” for a type.

impl Eq for CidSet

impl Hash for CidSet

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for CidSet

fn cmp(&self, other: &CidSet) -> 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.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for CidSet

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for CidSet

fn partial_cmp(&self, other: &CidSet) -> 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

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