new_macro
The Rust macro derives a new function with attribute for simplified struct instantiation. It eliminates repetitive code and enhances readability.
Usage
To use the new_macro
macro derive in your project, follow these steps:
- Import the
new_macro
crate in your code:
use new_macro::New;
- Annotate your struct with the New attribute:
#[derive(New)]
struct MyStruct {
a: u32,
b: bool,
c: i32
// Other attributes...
}
The macro will generate a new function for your struct that accepts arguments:
let instance = MyStruct::new(34, true, 3); // Create an instance
Please note that the arguments passed to the new function should match the order and type of the struct's attributes.
