Struct LanguageCode 

pub struct LanguageCode(/* private fields */);

ISO 639-1 language code newtype (two lowercase ASCII letters, e.g. "en").

Construction always validates the code; use LanguageCode::new or LanguageCode::try_from.

Implementations

impl LanguageCode

pub fn new(code: &str) -> Result<Self, CaptionGenError>

Create a validated ISO 639-1 language code.

The code must be exactly two ASCII lowercase letters (a-z).

Errors

Returns CaptionGenError::InvalidParameter if the code is not exactly two lowercase ASCII letters.

pub fn as_str(&self) -> &str

Return the inner code string slice.

Trait Implementations

impl Clone for LanguageCode

fn clone(&self) -> LanguageCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LanguageCode

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

Formats the value using the given formatter.

impl Display for LanguageCode

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

Formats the value using the given formatter.

impl Hash for LanguageCode

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 PartialEq for LanguageCode

fn eq(&self, other: &LanguageCode) -> 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 TryFrom<&str> for LanguageCode

type Error = CaptionGenError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for LanguageCode

type Error = CaptionGenError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.
