Struct RawID

pub struct RawID {
    pub language: u64,
    pub script: Option<u32>,
    pub region: Option<u32>,
}

RawID

Example

use lang_id::{LangID, RawID};

const fn id_und() -> LangID {
  RawID::new(6581877, None, None).into_lang_id()
}

assert_eq!(id_und().language, "und");

Fields

language: u64

script: Option<u32>

region: Option<u32>

Implementations

impl RawID

pub const fn new( language: u64, script: Option<u32>, region: Option<u32>, ) -> Self

pub const fn try_from_str( language: &str, script: &str, region: &str, ) -> Result<Self, ParseError>

Attempts to construct a Raw language ID from individual BCP 47 components.

Example

use lang_id::RawID;

let lzh = RawID::try_from_str("lzh", "Hant", "")?;

#[cfg(feature = "compact_str")]
assert_eq!(
  lzh.to_string(),
  "/*lzh-Hant*/ RawID::new(6847084, Some(1953390920), None).into_lang_id()"
);

pub fn to_bcp47(&self) -> CompactString

Available on crate feature compact_str only.

Converts the language identifier to a BCP47-compliant string representation.

Constructs a string in language[-script][-region] format.

use lang_id::RawID;

let id = RawID::try_from_str("es", "", "419")?;
let bcp47 = id.to_bcp47();
assert_eq!(bcp47, "es-419");

pub const fn into_lang_id(self) -> LangID

Warn: This function is unsafe.

Since Option<T>.map(|x| y) cannot be used in const fn in rust 1.85, use match expressions instead.

Trait Implementations

impl Clone for RawID

fn clone(&self) -> RawID

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RawID

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

Formats the value using the given formatter.

impl Default for RawID

fn default() -> RawID

Returns the “default value” for a type.

impl Display for RawID

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

Formats the value using the given formatter.

impl Hash for RawID

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 RawID

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

impl PartialEq for RawID

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for RawID

fn partial_cmp(&self, other: &RawID) -> 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.
