#[repr(C)]
pub struct ObjectTemplate(_);

Expand description

An ObjectTemplate is used to create objects at runtime.

Properties added to an ObjectTemplate are added to each object created from the ObjectTemplate.

Panics

Panics if both getter and setter are None.

source

pub fn set_immutable_proto(&self)
