Struct v8::Module

source ·
#[repr(C)]
pub struct Module(_);
Expand description

A compiled JavaScript module.

Implementations§

Returns the module’s current status.

For a module in kErrored status, this returns the corresponding exception.

Returns the ModuleRequests for this module.

For the given source text offset in this module, returns the corresponding Location with line and column numbers.

Returns the V8 hash value for this value. The current implementation uses a hidden property to store the identity hash.

The return value will never be 0. Also, it is not guaranteed to be unique.

Returns the underlying script’s id.

The module must be a SourceTextModule and must not have an Errored status.

Returns the namespace object of this module.

The module’s status must be at least kInstantiated.

Instantiates the module and its dependencies.

Returns an empty Maybe if an exception occurred during instantiation. (In the case where the callback throws an exception, that exception is propagated.)

NOTE: requires to set --harmony-import-assertions V8 flag.

Evaluates the module and its dependencies.

If status is kInstantiated, run the module’s code. On success, set status to kEvaluated and return the completion value; on failure, set status to kErrored and propagate the thrown exception (which is then also available via |GetException|).

Returns whether the module is a SourceTextModule.

Returns whether the module is a SyntheticModule.

Creates a new SyntheticModule with the specified export names, where evaluation_steps will be executed upon module evaluation. export_names must not contain duplicates. module_name is used solely for logging/debugging and doesn’t affect module behavior.

Set this module’s exported value for the name export_name to the specified export_value. This method must be called only on Modules created via create_synthetic_module. An error will be thrown if export_name is not one of the export_names that were passed in that create_synthetic_module call. Returns Some(true) on success, None if an error was thrown.

Methods from Deref<Target = Data>§
