pub struct Message<S> {

Expand description

Message node represents the most common Entry in an FTL Resource.

A message is a localization unit with a Identifier unique within a given Resource, and a value or attributes with associated Pattern.

A message can contain a simple text value, or a compound combination of value and attributes which together can be used to localize a complex User Interface element.

Finally, each Message may have an associated Comment.

§Example

use fluent_syntax::parser;
use fluent_syntax::ast;

let ftl = r#"

hello-world = Hello, World!

"#;

let resource = parser::parse(ftl)
    .expect("Failed to parse an FTL resource.");

assert_eq!(
    resource,
    ast::Resource {
        body: vec![
            ast::Entry::Message(ast::Message {
                id: ast::Identifier {
                    name: "hello-world"
                },
                value: Some(ast::Pattern {
                    elements: vec![
                        ast::PatternElement::TextElement {
                            value: "Hello, World!"
                        }
                    ]
                }),
                attributes: vec![],
                comment: None,
            })
        ]
    }
);
