Trait FromZendObject

pub trait FromZendObject<'a>: Sized {
    // Required method
    fn from_zend_object(obj: &'a ZendObject) -> Result<Self>;
}

FromZendObject is implemented by types which can be extracted from a Zend object.

Normal usage is through the helper method ZendObject::extract:

let obj: ZendObject = ...;
let repr: String = obj.extract();
let props: HashMap = obj.extract();

Should be functionally equivalent to casting an object to another compatible type.

Required Methods

fn from_zend_object(obj: &'a ZendObject) -> Result<Self>

Extracts Self from the source ZendObject.

Errors

If the conversion fails, an Error is returned.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
