Expand description

this is the internal abstract loader which is used to actually load the modules

Required Methods§

source

fn normalize_path( &self, q_ctx: &QuickJsRealmAdapter, ref_path: &str, path: &str, ) -> Option<String>

the normalize methods is used to translate a possible relative path to an absolute path of a module it doubles as a method to see IF a module can actually be loaded by a module loader (return None if the module can not be found)

source

fn load_module( &self, q_ctx: &QuickJsRealmAdapter, absolute_path: &str, ) -> Result<*mut JSModuleDef, JsError>

load the Module

source

fn has_module(&self, q_ctx: &QuickJsRealmAdapter, absolute_path: &str) -> bool

has module is used to check if a loader can provide a certain module, this is currently used to check which loader should init a native module

source

unsafe fn init_module( &self, q_ctx: &QuickJsRealmAdapter, module: *mut JSModuleDef, ) -> Result<(), JsError>

init a module, currently used to init native modules

§Safety

be safe with the moduledef ptr
