Struct reaper_test::PluginContext

pub struct PluginContext { /* private fields */ }

This represents the context which is needed to access REAPER functions from plug-ins.

Once obtained, it is supposed to be passed to Reaper::load().

Implementations

impl PluginContext

pub unsafe fn from_extension_plugin(
    h_instance: *mut c_void,
    rec: reaper_plugin_info_t,
    static_context: StaticExtensionPluginContext
) -> Result<PluginContext, ContextFromExtensionPluginError>

Creates a plug-in context from an extension entry point plug-in info.

It requires a module handle and the pointer to a reaper_plugin_info_t struct. REAPER provides both when calling the ReaperPluginEntry function (the main entry point for any extension plug-in).

It’s recommended to use the reaper_extension_plugin macro in the reaper-macros crate instead of calling this function directly.

Errors

Returns an error if the given plug-in info is not suitable for loading REAPER functions.

Safety

REAPER can crash if you pass an invalid pointer.

pub fn from_vst_plugin(
    host: &HostCallback,
    static_context: StaticVstPluginContext
) -> Result<PluginContext, ContextFromVstPluginError>

Creates a plug-in context from a VST host callback.

It requires the host callback which vst-rs passes to the plugin’s new() function.

Errors

Returns an error if the given host callback is not suitable for loading REAPER functions.

pub unsafe fn GetFunc(&self, name: *const i8) -> *mut c_void

Returns a generic API function by its name.

Safety

REAPER can crash if you pass an invalid pointer.

pub fn h_instance(&self) -> *mut c_void

On Windows, this returns the HINSTANCE passed to DllMain (VST plug-ins) or ReaperPluginEntry (extension plug-ins).

The returned HINSTANCE represents the handle of the module (DLL) containing the plug-in.

On Linux, this returns null.

pub fn swell_function_provider(
    &self
) -> Option<unsafe extern "C" fn(*const i8) -> *mut c_void>

On Linux, this returns a pointer to a function for getting a generic SWELL API function by its name.

On Windows, this returns None.

pub fn type_specific(&self) -> &TypeSpecificPluginContext

Returns the type-specific plug-in context.

pub fn is_in_main_thread(&self) -> bool

Returns whether we are currently in the main thread.

Trait Implementations

impl Clone for PluginContext

fn clone(&self) -> PluginContext

Returns a copy of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PluginContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq<PluginContext> for PluginContext

fn eq(&self, other: &PluginContext) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
