Struct RawExtensionImplementation 

pub struct RawExtensionImplementation { /* private fields */ }

A pointer to an extension’s implementation struct.

This type is used to type-erase a reference to the implementation struct of an extension before transferring it to the consumer through get_extension.

This type is also used to enforce the extension pointer is always valid, as extension implementations produced from Clack always come from statics and therefore always have the 'static lifetime.

Note this is not the case for all CLAP plugins: extension pointers are only guaranteed to be valid for the lifetime of the instance (plugin or host) they originate from.

Use the RawExtension type to properly use and track the lifetime of extension pointers on the consumer-side.

Implementations

impl RawExtensionImplementation

pub const fn new<I>(implementation: &'static I) -> RawExtensionImplementation

Creates a new pointer from a 'static reference to an implementation struct.

pub const fn as_ptr(&self) -> NonNull<c_void>

Returns the raw pointer to the extension implementation struct.

This pointer is always valid and never dangling, as it originates from a 'static reference.
