Struct fluent_bundle::FluentArgs

pub struct FluentArgs<'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."
);
