Expand description

Provides functionality for running Nushell plugins from a Nushell engine.

Structs§

PersistentPlugin: A box that can keep a plugin that was spawned persistent for further uses. The plugin may or may not be currently running. [.get()] gets the currently running plugin, or spawns it if it’s not running.
PluginCustomValueWithSource: Wraps a PluginCustomValue together with its PluginSource, so that the CustomValue methods can be implemented by calling the plugin, and to ensure that any custom values sent to a plugin came from it originally.
PluginDeclaration: The command declaration proxy used within the engine for all plugin commands.
PluginExecutionCommandContext: The execution context of a plugin command. Can be borrowed.
PluginGc: Plugin garbage collector
PluginInterfaceManager: Manages reading and dispatching messages for [PluginInterface]s.
PluginSource: The source of a custom value or plugin command. Includes a weak reference to the persistent plugin so it can be retrieved.

GetPlugin: Anything that can produce a plugin interface.
PluginExecutionContext: Object safe trait for abstracting operations required of the plugin context.
WithSource: Helper trait for adding a source to a PluginCustomValue

add_plugin_to_working_set: Find PersistentPlugin with the given identity in the working_set, or construct it if it doesn’t exist.
create_command: Spawn the command for a plugin, in the given mode. After spawning, it can be passed to make_plugin_interface() to get a [PluginInterface].
get_plugin_encoding: Determine the plugin’s encoding from a freshly opened stream.
load_plugin_file: Load the definitions from the plugin file into the engine state
load_plugin_registry_item: Load a definition from the plugin file into the engine state
