`#[php]` Attributes

There are a number of attributes that can be used to annotate elements in your extension.

Multiple #[php] attributes will be combined. For example, the following will be identical:

#![cfg_attr(windows, feature(abi_vectorcall))]
extern crate ext_php_rs;
use ext_php_rs::prelude::*;
#[php_function]
#[php(name = "hi_world")]
#[php(defaults(a = 1, b = 2))]
fn hello_world(a: i32, b: i32) -> i32 {
    a + b
}
fn main() {}

#![cfg_attr(windows, feature(abi_vectorcall))]
extern crate ext_php_rs;
use ext_php_rs::prelude::*;
#[php_function]
#[php(name = "hi_world", defaults(a = 1, b = 2))]
fn hello_world(a: i32, b: i32) -> i32 {
    a + b
}
fn main() {}

Which attributes are available depends on the element you are annotating:
