Enum ext_php_rs::props::Property

pub enum Property<'a, T> {
    Field(Box<dyn Fn(&mut T) -> &mut dyn Prop<'_> + Send + Sync>),
    Method {
        get: PropertyGetter<'a, T>,
        set: PropertySetter<'a, T>,
    },
}

Represents a property added to a PHP class.

There are two types of properties:

• Field properties, where the data is stored inside a struct field.
• Method properties, where getter and/or setter functions are provided, which are used to get and set the value of the property.

Variants

Field(Box<dyn Fn(&mut T) -> &mut dyn Prop<'_> + Send + Sync>)

Method

Fields

get: PropertyGetter<'a, T>

set: PropertySetter<'a, T>

Implementations

impl<'a, T: 'a> Property<'a, T>

pub fn field<F>(f: F) -> Self

where F: Fn(&mut T) -> &mut dyn Prop<'_> + Send + Sync + 'static,

Creates a field property.

Parameters

• f - The function used to get a mutable reference to the property.

Examples

struct Test {
    pub a: i32,
}

let prop: Property<Test> = Property::field(|test: &mut Test| &mut test.a);

pub fn method<V>( get: Option<fn(_: &T) -> V>, set: Option<fn(_: &mut T, _: V)> ) -> Self

where for<'b> V: IntoZval + FromZval<'b> + 'a,

Creates a method property with getters and setters.

If either the getter or setter is not given, an exception will be thrown when attempting to retrieve/set the property.

Parameters

• get - Function used to get the value of the property, in an Option.
• set - Function used to set the value of the property, in an Option.

Examples

struct Test;

impl Test {
    pub fn get_prop(&self) -> String {
        "Hello".into()
    }

    pub fn set_prop(&mut self, val: String) {
        println!("{}", val);
    }
}

let prop: Property<Test> = Property::method(Some(Test::get_prop), Some(Test::set_prop));

pub fn get(&self, self_: &'a mut T, retval: &mut Zval) -> PhpResult

Attempts to retrieve the value of the property from the given object self_.

The value of the property, if successfully retrieved, is loaded into the given Zval retval. If unsuccessful, a PhpException is returned inside the error variant of a result.

Parameters

• self_ - The object to retrieve the property from.
• retval - The Zval to load the value of the property into.

Returns

Nothing upon success, a PhpException inside an error variant when the property could not be retrieved.

Examples

struct Test {
    pub a: i32,
}

let prop: Property<Test> = Property::field(|obj: &mut Test| &mut obj.a);

let mut test = Test { a: 500 };
let mut zv = Zval::new();
prop.get(&mut test, &mut zv).unwrap();
assert_eq!(zv.long(), Some(500));

pub fn set(&self, self_: &'a mut T, value: &Zval) -> PhpResult

Attempts to set the value of the property inside the given object self_.

The new value of the property is supplied inside the given Zval value. If unsuccessful, a PhpException is returned inside the error variant of a result.

Parameters

• self_ - The object to set the property in.
• value - The Zval containing the new content for the property.

Returns

Nothing upon success, a PhpException inside an error variant when the property could not be set.

Examples

struct Test {
    pub a: i32,
}

let prop: Property<Test> = Property::field(|obj: &mut Test| &mut obj.a);

let mut test = Test { a: 500 };
let zv = 100.into_zval(false).unwrap();
prop.set(&mut test, &zv).unwrap();
assert_eq!(test.a, 100);
