Trait IntoZval

pub trait IntoZval: Sized {
    const TYPE: DataType;
    const NULLABLE: bool;

    // Required method
    fn set_zval(self, zv: &mut Zval, persistent: bool) -> Result<()>;

    // Provided method
    fn into_zval(self, persistent: bool) -> Result<Zval> { ... }
}

Expand description

Provides implementations for converting Rust primitive types into PHP zvals. Alternative to the built-in Rust From and TryFrom implementations, allowing the caller to specify whether the Zval contents will persist between requests.

Required Associated Constants§

const TYPE: DataType

The corresponding type of the implemented value in PHP.

const NULLABLE: bool

Whether converting into a Zval may result in null.

Required Methods§

fn set_zval(self, zv: &mut Zval, persistent: bool) -> Result<()>

Sets the content of a pre-existing zval. Returns a result containing nothing if setting the content was successful.

§Parameters

zv - The Zval to set the content of.
persistent - Whether the contents of the Zval will persist between requests.

§Errors

If setting the content fails, an Error is returned.

Provided Methods§

fn into_zval(self, persistent: bool) -> Result<Zval>

Converts a Rust primitive type into a Zval. Returns a result containing the Zval if successful.

§Parameters

persistent - Whether the contents of the Zval will persist between requests.

§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.
