Struct koto_runtime::MethodContext
source · pub struct MethodContext<'a, T> {
pub args: &'a [KValue],
pub vm: &'a KotoVm,
/* private fields */
}
Expand description
Context provided to a function that implements an object method
This is used by the #[koto_impl]
macro when generating wrappers for functions tagged with
#[koto_method]
. A native function is called with a CallContext, and for functions that
implement object methods a MethodContext is produced when the first call argument is a
KObject.
Fields§
§args: &'a [KValue]
The method call arguments
vm: &'a KotoVm
A VM that can be used by the method for operations that require a runtime

impl<'a, T: KotoObject> MethodContext<'a, T>
sourcepub fn new(object: &'a KObject, args: &'a [KValue], vm: &'a KotoVm) -> Self
pub fn new(object: &'a KObject, args: &'a [KValue], vm: &'a KotoVm) -> Self
Makes a new method context
sourcepub fn instance(&self) -> Result<Borrow<'_, T>>
pub fn instance(&self) -> Result<Borrow<'_, T>>
Attempts to immutably borrow the object instance
sourcepub fn instance_mut(&self) -> Result<BorrowMut<'_, T>>
pub fn instance_mut(&self) -> Result<BorrowMut<'_, T>>
Attempts to mutably borrow the object instance
sourcepub fn instance_result(&self) -> Result<KValue>
pub fn instance_result(&self) -> Result<KValue>
Helper for methods that need to return a clone of the instance as the method result
