Struct EditorContext 

pub struct EditorContext {
    pub begin_edit: Arc<dyn Fn(u32) + Send + Sync>,
    pub set_param: Arc<dyn Fn(u32, f64) + Send + Sync>,
    pub end_edit: Arc<dyn Fn(u32) + Send + Sync>,
    pub request_resize: Arc<dyn Fn(u32, u32) -> bool + Send + Sync>,
    pub get_param: Arc<dyn Fn(u32) -> f64 + Send + Sync>,
    pub get_param_plain: Arc<dyn Fn(u32) -> f64 + Send + Sync>,
    pub format_param: Arc<dyn Fn(u32) -> String + Send + Sync>,
    pub get_meter: Arc<dyn Fn(u32) -> f32 + Send + Sync>,
}

Context passed to Editor::open(). Provides communication with the host and parameter store.

All fields are Arc-wrapped, so cloning is cheap (reference count bump).

Fields

begin_edit: Arc<dyn Fn(u32) + Send + Sync>

set_param: Arc<dyn Fn(u32, f64) + Send + Sync>

end_edit: Arc<dyn Fn(u32) + Send + Sync>

request_resize: Arc<dyn Fn(u32, u32) -> bool + Send + Sync>

get_param: Arc<dyn Fn(u32) -> f64 + Send + Sync>

Read a parameter’s normalized value from the plugin (for host→GUI sync).

get_param_plain: Arc<dyn Fn(u32) -> f64 + Send + Sync>

Read a parameter’s plain value from the plugin.

format_param: Arc<dyn Fn(u32) -> String + Send + Sync>

Format a parameter’s current value as a display string.

get_meter: Arc<dyn Fn(u32) -> f32 + Send + Sync>

Read a meter value (0.0–1.0) by meter ID. Used for level meters. Returns 0.0 if the meter ID doesn’t exist.

Trait Implementations

impl Clone for EditorContext

fn clone(&self) -> EditorContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.
