Struct rquickjs_core::module::ModuleData

pub struct ModuleData { /* private fields */ }

The data required to load a module, either from source or native.

Implementations

impl ModuleData

pub fn source<N, S>(name: N, source: S) -> Self

where N: Into<Vec<u8>>, S: Into<Vec<u8>>,

Create module data for a module loaded from source.

pub unsafe fn bytecode<N, S>(name: N, bytecode: S) -> Self

where N: Into<Vec<u8>>, S: Into<Cow<'static, [u8]>>,

Create module data for a module loaded from source.

Safety

User must ensure that the bytecode is valid QuickJS bytecode.

pub fn native<D, N>(name: N) -> Self

where D: ModuleDef, N: Into<Vec<u8>>,

Create module data for a module loaded from a native Rust definition.

pub unsafe fn raw<N>(name: N, load_fn: ModuleLoadFn) -> Self

where N: Into<Vec<u8>>,

Create module data for a module loaded from a native Rust definition.

Safety

User must ensure that load_fn behaves like a loader function.

The function must take a context and a c string without taking ownership of either values and return a pointer to qjs::JSModuleDef, or a null pointer if there was some error.

pub fn kind(&self) -> &ModuleDataKind

Returns the kind of ModuleData.

pub fn declare<'js>(self, ctx: Ctx<'js>) -> Result<()>

Declare the module defined in the ModuleData.

pub unsafe fn unsafe_declare<'js>(self, ctx: Ctx<'js>) -> Result<Module<'js>>

Declare the module defined in the ModuleData.

Safety

This method returns an unevaluated module. It is UB to hold unto unevaluated modules across any call to a module function which can invalidate unevaluated modules and returned an error.

Trait Implementations

impl Clone for ModuleData

fn clone(&self) -> ModuleData

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ModuleData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
