Struct rustc_error_messages::FluentArgs

pub struct FluentArgs<'args>(Vec<(Cow<'args, str>, FluentValue<'args>)>);

A map of arguments passed from the code to the localization to be used for message formatting.

Example

use fluent_bundle::{FluentArgs, FluentBundle, FluentResource};

let mut args = FluentArgs::new();
args.set("user", "John");
args.set("emailCount", 5);

let res = FluentResource::try_new(r#"

msg-key = Hello, { $user }. You have { $emailCount } messages.

"#.to_string())
    .expect("Failed to parse FTL.");

let mut bundle = FluentBundle::default();

// For this example, we'll turn on BiDi support.
// Please, be careful when doing it, it's a risky move.
bundle.set_use_isolating(false);

bundle.add_resource(res)
    .expect("Failed to add a resource.");

let mut err = vec![];

let msg = bundle.get_message("msg-key")
    .expect("Failed to retrieve a message.");
let value = msg.value()
    .expect("Failed to retrieve a value.");

assert_eq!(
    bundle.format_pattern(value, Some(&args), &mut err),
    "Hello, John. You have 5 messages."
);

Trait Implementations

impl<'args> Debug for FluentArgs<'args>

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

Formats the value using the given formatter.

impl<'args> Default for FluentArgs<'args>

fn default() -> FluentArgs<'args>

Returns the “default value” for a type.

impl<'args, K, V> FromIterator<(K, V)> for FluentArgs<'args>

where K: Into<Cow<'args, str>>, V: Into<FluentValue<'args>>,

fn from_iter<I>(iter: I) -> FluentArgs<'args>

where I: IntoIterator<Item = (K, V)>,

Creates a value from an iterator.

impl<'args> IntoIterator for FluentArgs<'args>

type Item = (Cow<'args, str>, FluentValue<'args>)

The type of the elements being iterated over.

type IntoIter = IntoIter<(Cow<'args, str>, FluentValue<'args>)>

Which kind of iterator are we turning this into?

fn into_iter(self) -> IntoIter<(Cow<'args, str>, FluentValue<'args>)>

Creates an iterator from a value.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
