Struct Class 

pub struct Class {
    pub name: String,
    pub type_id: TypeId,
    pub register_hooks: Vec<RegisterHook>,
    /* private fields */
}

Class that can be registered with Oso.

A class represents an entity, such as an actor or a resource. It is typically backed by a Rust struct and can carry some internal state, as well as have methods that can be made accessible from within the policy file.

While the instance of the class itself is stored as a PolarValue::Instance, the Class struct contains metadata, such as the constructor, attributes, instance methods, comparison functions as well as the name.

Fields

name: String

The class name. Defaults to std::any::type_name.

type_id: TypeId

Type ID of the class.

register_hooks: Vec<RegisterHook>

Hooks to be called on the class once it’s been registered with host.

Implementations

impl Class

pub fn builder<T: 'static>() -> ClassBuilder<T>

Builder instance to build class.

Use this when you want to hook your own class into Oso. See ClassBuilder for usage examples.

pub fn init(&self, fields: Vec<PolarValue>) -> Result<Instance>

Initialize new class instance.

pub fn call(&self, attr: &str, args: Vec<PolarValue>) -> Result<PolarValue>

Call class method attr on self with arguments from args.

Returns the result as a PolarValue.

Trait Implementations

impl Clone for Class

fn clone(&self) -> Class

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PolarClass for Class

fn get_polar_class() -> Class

Returns the Class ready for registration

fn get_polar_class_builder() -> ClassBuilder<Self>

Returns the partially defined Class for this type.
