Struct PluginContext 

pub struct PluginContext { /* private fields */ }

Plugin context that provides access to VirtualDJ API functions

This struct holds the plugin pointer and callbacks, allowing safe access to VirtualDJ state information like track metadata, position, BPM, etc.

Example

let context = PluginContext::new(plugin_ptr, &callbacks);
let title = context.get_info_string("deck 1 get_title")?;
let position = context.get_info_double("deck 1 get_position")?;

Implementations

impl PluginContext

pub fn new(plugin: *mut VdjPlugin, callbacks: &VdjCallbacks) -> Self

Create a new plugin context

Arguments

• plugin - Pointer to the VdjPlugin struct
• callbacks - Reference to the VdjCallbacks struct

Safety

The plugin pointer must be valid and the callbacks must remain valid for the lifetime of this context.

pub fn get_info_double(&self, command: &str) -> Result<f64>

Query VirtualDJ for a double/numeric value

Arguments

• command - The VDJ script command (e.g., “deck 1 get_position”)

Returns

A Result containing the numeric value, or an error if the command fails

pub fn get_info_string(&self, command: &str) -> Result<String>

Query VirtualDJ for a string value

Arguments

• command - The VDJ script command (e.g., “deck 1 get_title”)

Returns

A Result containing the string value, or an error if the command fails

pub fn send_command(&self, command: &str) -> Result<()>

Send a command to VirtualDJ

Arguments

• command - The VDJ script command (e.g., “deck 1 play”)

Returns

Ok(()) if successful, or an error if the command fails
