Struct json_ld::LangString

pub struct LangString<J: Json> { /* private fields */ }

Language string.

A language string is a string tagged with language and reading direction information.

A valid language string is associated to either a language tag or a direction, or both.

Implementations

impl<J: Json> LangString<J>

pub fn new(
    str: LiteralString<J>,
    language: Option<LenientLanguageTagBuf>,
    direction: Option<Direction>
) -> Result<Self, LiteralString<J>>

Create a new language string.

pub fn as_string(&self) -> &LiteralString<J>

Reference to the underlying str.

pub fn as_str(&self) -> &str

Reference to the underlying str.

pub fn language(&self) -> Option<LenientLanguageTag<'_>>

Gets the associated language tag, if any.

pub fn set_language(
    &mut self,
    language: Option<LenientLanguageTagBuf>
) -> Result<(), InvalidLangString>

Sets the associated language tag.

If None is given, the direction must be set, otherwise this function will fail with an InvalidLangString error.

pub fn direction(&self) -> Option<Direction>

Gets the associated direction, if any.

pub fn set_direction(
    &mut self,
    direction: Option<Direction>
) -> Result<(), InvalidLangString>

Sets the associated direction.

If None is given, a language tag must be set, otherwise this function will fail with an InvalidLangString error.

pub fn set(
    &mut self,
    language: Option<LenientLanguageTagBuf>,
    direction: Option<Direction>
) -> Result<(), InvalidLangString>

Set both the language tag and direction.

If both language and direction are None, this function will fail with an InvalidLangString error.
