Struct rusteron_rb::ManagedCResource

pub struct ManagedCResource<T> { /* private fields */ }

A custom struct for managing C resources with automatic cleanup.

It handles initialisation and clean-up of the resource and ensures that resources are properly released when they go out of scope.

Implementations

impl<T> ManagedCResource<T>

pub fn new( init: impl FnOnce(*mut *mut T) -> i32, cleanup: impl FnMut(*mut *mut T) -> i32 + 'static, cleanup_struct: bool, ) -> Result<Self, AeronCError>

Creates a new ManagedCResource with a given initializer and cleanup function.

The initializer is a closure that attempts to initialize the resource. If initialization fails, the initializer should return an error code. The cleanup function is used to release the resource when it’s no longer needed. cleanup_struct where it should clean up the struct in rust

pub fn new_borrowed(value: *const T) -> Self

pub fn get(&self) -> *mut T

Gets a raw pointer to the resource.

pub fn close(&mut self) -> Result<(), AeronCError>

Closes the resource by calling the cleanup function.

If cleanup fails, it returns an AeronError.
