Trait 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.

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.
