Struct ScriptManager

pub struct ScriptManager { /* private fields */ }

ScriptManager holds all the scripts found, it can be constructed with ScriptManager::default
Initially its empty, to populate it, we can use one of the methods to add scripts, currently only ScriptManager::add_scripts_by_path is provided

Implementations

impl ScriptManager

pub fn add_scripts_by_path<P: AsRef<Path>>( &mut self, path: P, version: Version, ) -> Result<(), Error>

Look for scripts in the specified folder
It requires specifying a VersionReq so the script manager can check for incompatibility and if that’s the case it will return an error: Error::ScriptVersionMismatch\

let mut sm = ScriptManager::default();
let scripts_path: std::path::PathBuf = todo!(); // Defined by the user
const VERSION: &'static str = concat!("main_crate-", env!("CARGO_PKG_VERSION"));
sm.add_scripts_by_path(scripts_path, Version::parse(VERSION).expect("version is correct"));

pub unsafe fn add_dynamic_scripts_by_path<P: AsRef<Path>>( &mut self, path: P, version: Version, ) -> Result<(), Error>

Same as ScriptManager::add_scripts_by_path but looks for dynamic libraries instead

Safety

See https://docs.rs/libloading/0.7.1/libloading/struct.Library.html#safety

pub fn trigger<'a, H: 'static + Hook>( &'a mut self, hook: H, ) -> impl Iterator<Item = Result<<H as Hook>::Output, Error>> + 'a

Trigger a hook All scripts that are active and that are listening for this particular hook will receive it

pub fn scripts(&self) -> &[Script]

List of current scripts

pub fn scripts_mut(&mut self) -> &mut [Script]

Mutable list of current scripts, useful for activating/deactivating a script
