Trait rustc_error_messages::FluentType

pub trait FluentType:
    Debug
    + AnyEq
    + 'static {
    // Required methods
    fn duplicate(&self) -> Box<dyn FluentType + Send>;
    fn as_string(&self, intls: &IntlLangMemoizer) -> Cow<'static, str>;
    fn as_string_threadsafe(
        &self,
        intls: &IntlLangMemoizer,
    ) -> Cow<'static, str>;
}

Custom types can implement the FluentType trait in order to generate a string value for use in the message generation process.

Required Methods

fn duplicate(&self) -> Box<dyn FluentType + Send>

Create a clone of the underlying type.

fn as_string(&self, intls: &IntlLangMemoizer) -> Cow<'static, str>

Convert the custom type into a string value, for instance a custom DateTime type could return “Oct. 27, 2022”.

fn as_string_threadsafe(&self, intls: &IntlLangMemoizer) -> Cow<'static, str>

Convert the custom type into a string value, for instance a custom DateTime type could return “Oct. 27, 2022”. This operation is provided the threadsafe IntlLangMemoizer.

Trait Implementations

impl PartialEq for dyn FluentType + Send

fn eq(&self, other: &(dyn FluentType + Send + 'static)) -> 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.
