Macros

ext-php-rs comes with a set of macros that are used to annotate types which are to be exported to PHP. This allows you to write Rust-like APIs that can be used from PHP without fiddling around with zvals.

• php_module - Defines the function used by PHP to retrieve your extension.
• [php_startup] - Defines the extension startup function used by PHP to initialize your extension.
• php_function - Used to export a Rust function to PHP.
• php_class - Used to export a Rust struct or enum as a PHP class.
• php_impl - Used to export a Rust impl block to PHP, including all methods and constants.
• php_const - Used to export a Rust constant to PHP as a global constant.
• php_extern - Attribute used to annotate extern blocks which are deemed as PHP functions.
