Implementations§
source§impl<'a> ZendCallable<'a>
impl<'a> ZendCallable<'a>
sourcepub fn new(callable: &'a Zval) -> Result<Self>
pub fn new(callable: &'a Zval) -> Result<Self>
Attempts to create a new ZendCallable from a zval.
Parameters
callable- The underlyingZvalthat is callable.
Errors
Returns an error if the Zval was not callable.
sourcepub fn new_owned(callable: Zval) -> Result<Self>
pub fn new_owned(callable: Zval) -> Result<Self>
Attempts to create a new ZendCallable by taking ownership of a Zval.
Returns a result containing the callable if the zval was callable.
Parameters
callable- The underlyingZvalthat is callable.
sourcepub fn try_from_name(name: &str) -> Result<Self>
pub fn try_from_name(name: &str) -> Result<Self>
Attempts to create a new ZendCallable from a function name. Returns
a result containing the callable if the function existed and was
callable.
Parameters
name- Name of the callable function.
Example
use ext_php_rs::types::ZendCallable;
let strpos = ZendCallable::try_from_name("strpos").unwrap();
let result = strpos.try_call(vec![&"hello", &"e"]).unwrap();
assert_eq!(result.long(), Some(1));sourcepub fn try_call(&self, params: Vec<&dyn IntoZvalDyn>) -> Result<Zval>
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.
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.
Returns
Returns the result wrapped in Ok upon success. If calling the
callable fails, or an exception is thrown, an Err is returned.
Example
use ext_php_rs::types::ZendCallable;
let strpos = ZendCallable::try_from_name("strpos").unwrap();
let result = strpos.try_call(vec![&"hello", &"e"]).unwrap();
assert_eq!(result.long(), Some(1));
