Trait ext_php_rs::convert::FromZval

pub trait FromZval<'a>: Sized {
    const TYPE: DataType;

    // Required method
    fn from_zval(zval: &'a Zval) -> Option<Self>;
}

Allows zvals to be converted into Rust types in a fallible way. Reciprocal of the IntoZval trait.

Required Associated Constants

const TYPE: DataType

The corresponding type of the implemented value in PHP.

Required Methods

fn from_zval(zval: &'a Zval) -> Option<Self>

Attempts to retrieve an instance of Self from a reference to a Zval.

Parameters

• zval - Zval to get value from.

Object Safety

This trait is not object safe.
