Trait Extension 

pub unsafe trait Extension:
    Sized
    + Copy
    + Send
    + Sync
    + 'static {
    type ExtensionSide: ExtensionSide;

    const IDENTIFIERS: &'static [&'static CStr];

    // Required method
    unsafe fn from_raw(raw: RawExtension<Self::ExtensionSide>) -> Self;
}

A type representing a CLAP extension pointer.

The role of this trait is to tie a type to a standard CLAP extension identifier. This is then used by the Clack APIs to always match the correct extension type from its identifier.

This trait also defines how an extension pointer should be transformed to a reference to the extension type.

Safety

The IDENTIFIER must match the official identifier for the given extension, otherwise the extension data could be misinterpreted, leading to Undefined Behavior.

Required Associated Constants

const IDENTIFIERS: &'static [&'static CStr]

The standard identifier for this extension.

Required Associated Types

type ExtensionSide: ExtensionSide

Whether this is a host extension or a plugin extension

Required Methods

unsafe fn from_raw(raw: RawExtension<Self::ExtensionSide>) -> Self

Returns an instance of the extension from a given extension pointer.

Safety

Callers must ensure the extension pointer points to the extension type that matches Self::IDENTIFIERS.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
