Struct druid::LocalizedString

pub struct LocalizedString<T> {
    pub(crate) key: &'static str,
    placeholder: Option<String<U20>>,
    args: Option<Vec<(&'static str, ArgSource<T>), U2>>,
    resolved: Option<String<U20>>,
}

A string that can be localized based on the current locale.

At its simplest, a LocalizedString is a key that can be resolved against a map of localized strings for a given locale.

Fields

key: &'static str

placeholder: Option<String<U20>>

args: Option<Vec<(&'static str, ArgSource<T>), U2>>

resolved: Option<String<U20>>

Methods

impl<T> LocalizedString<T>

pub const fn new(key: &'static str) -> Self

Create a new LocalizedString with the given key.

pub fn localized_str(&self) -> &str

Return the localized value for this string, or the placeholder, if the localization is missing, or the key if there is no placeholder.

impl<T: Data> LocalizedString<T>

pub fn with_arg(
    self,
    key: &'static str,
    f: fn(_: &T, _: &Env) -> ArgValue
) -> Self

Add a named argument and a corresponding ArgClosure. This closure is a function that will return a value for the given key from the current environment and data.

pub fn resolve<'a>(&'a mut self, data: &T, env: &Env) -> bool

Lazily compute the localized value for this string based on the provided environment and data.

Returns true if the current value of the string has changed.

Trait Implementations

impl<T: Clone> Clone for LocalizedString<T>

fn clone(&self) -> LocalizedString<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> From<LocalizedString<T>> for LabelText<T>

fn from(src: LocalizedString<T>) -> LabelText<T>

Performs the conversion.
