📝 About The Project

Provides macros for implementing traits and deriving functionality in the fuel-streams ecosystem.

[!NOTE] This crate is specifically modeled for the Fuel Data Systems project, and is not intended for general use outside of the project.

🚀 Usage

The Subject derive macro allows you to easily implement the Subject trait for your structs. It generates methods for parsing, building, and creating wildcards for your subject.

Example:

use fuel_streams_macros::subject::{Subject, IntoSubject, SubjectBuildable};

#[derive(Subject, Debug, Clone, Default)]
#[subject_wildcard = "test.>"]
#[subject_format = "test.{field1}.{field2}"]
struct TestSubject {
    field1: Option<String>,
    field2: Option<u32>,
}

// Create a new TestSubject
let subject = TestSubject {
    field1: Some("foo".to_string()),
    field2: Some(55),
};

// Parse the subject
assert_eq!(subject.parse(), "test.foo.55");

// Create a wildcard
assert_eq!(TestSubject::wildcard(None, Some(10)), "test.*.10");

// Create using the build method
let subject = TestSubject::build(Some("foo".into()), Some(55));
assert_eq!(subject.parse(), "test.foo.55");

// Create a new TestSubject with the builder pattern
let subject = TestSubject::new()
    .with_field1(Some("foo".to_string()))
    .with_field2(Some(55));
assert_eq!(subject.parse(), "test.foo.55");

// Convert to a string
assert_eq!(&subject.to_string(), "test.foo.55");
