Struct rquickjs_core::Module

pub struct Module<'js, S = Evaluated>(_, _);

Javascript module with certain exports and imports

Implementations

impl<'js> Module<'js>

pub fn name<N>(&self) -> Result<N> where
    N: FromAtom<'js>, 

Returns the name of the module

pub fn meta<T>(&self) -> Result<T> where
    T: FromJs<'js>, 

Return the import.meta object of a module

impl<'js> Module<'js>

pub fn new<N, S>(
    ctx: Ctx<'js>,
    name: N,
    source: S
) -> Result<Module<'js, Loaded<Script>>> where
    N: Into<Vec<u8>>,
    S: Into<Vec<u8>>, 

Create module from JS source

pub fn new_def<D, N>(
    ctx: Ctx<'js>,
    name: N
) -> Result<Module<'js, Loaded<Native>>> where
    D: ModuleDef,
    N: Into<Vec<u8>>, 

Create native JS module using ModuleDef

pub unsafe fn new_raw<N>(
    ctx: Ctx<'js>,
    name: N,
    load: ModuleLoadFn
) -> Result<Module<'js, Loaded<Native>>> where
    N: Into<Vec<u8>>, 

Create native JS module by calling init function (like js_module_init)

Safety

The load function should not crash. But it can throw exception and return null pointer in that case.

pub unsafe extern "C" fn init_raw<D>(
    ctx: *mut JSContext,
    name: *const c_char
) -> *mut JSModuleDef where
    D: ModuleDef, 

The function for loading native JS module

Safety

This function should only be called from js_module_init function.

impl<'js> Module<'js, Loaded<Script>>

pub fn read_object<B: AsRef<[u8]>>(ctx: Ctx<'js>, buf: B) -> Result<Self>

Load module from bytecode

pub fn read_object_const(ctx: Ctx<'js>, buf: &'static [u8]) -> Result<Self>

pub fn write_object(&self, byte_swap: bool) -> Result<Vec<u8>>

impl<'js> Module<'js, Loaded<Native>>

pub fn set<N, T>(&self, name: N, value: T) -> Result<()> where
    N: AsRef<str>,
    T: IntoJs<'js>, 

Set exported entry by name

NOTE: Exported entries should be added before module instantiating using Module::add.

impl<'js, S> Module<'js, Loaded<S>>

pub fn eval(self) -> Result<Module<'js, Evaluated>>

Evaluate a loaded module

To get access to module exports it should be evaluated first, in particular when you create module manually via Module::new.

pub fn into_loaded(self) -> Module<'js, Loaded>

Cast the specific loaded module to generic one

impl<'js> Module<'js, Created>

pub fn add<N>(&self, name: N) -> Result<()> where
    N: AsRef<str>, 

Add entry to module exports

NOTE: Added entries should be set after module instantiating using Module::set.

impl<'js> Module<'js>

pub fn get<N, T>(&self, name: N) -> Result<T> where
    N: AsRef<str>,
    T: FromJs<'js>, 

Return exported value by name

pub fn names<N>(&self) -> ExportNamesIter<'js, N> where
    N: FromAtom<'js>, 

This is supported on crate feature exports only.

Returns a iterator over the exported names of the module export.

pub fn entries<N, T>(&self) -> ExportEntriesIter<'js, N, T> where
    N: FromAtom<'js>,
    T: FromJs<'js>, 

This is supported on crate feature exports only.

Returns a iterator over the items the module export.
