Struct ext_php_rs::php::types::callable::Callable

pub struct Callable<'a>(_);

Acts as a wrapper around a callable Zval. Allows the owner to call the Zval as if it was a PHP function through the try_call method.

Implementations

impl<'a> Callable<'a>

pub fn new(callable: &'a Zval) -> Result<Self>

Attempts to create a new Callable from a zval.

Parameters

• callable - The underlying Zval that is callable.

Errors

Returns an error if the Zval was not callable.

pub fn new_owned(callable: Zval) -> Result<Self>

Attempts to create a new Callable by taking ownership of a Zval. Returns a result containing the callable if the zval was callable.

Parameters

• callable - TThe underlying Zval that is callable.

pub fn try_from_name(name: &str) -> Result<Self>

Attempts to create a new Callable from a function name. Returns a result containing the callable if the function existed and was callable.

Parameters

• name - Name of the callable function.

pub fn try_call(&self, params: Vec<&dyn IntoZvalDyn>) -> Result<Zval>

Attempts to call the callable with a list of arguments to pass to the function. Note that a thrown exception inside the callable is not detectable, therefore you should check if the return value is valid rather than unwrapping. Returns a result containing the return value of the function, or an error.

You should not call this function directly, rather through the call_user_func macro.

Parameters

• params - A list of parameters to call the function with.
