enum v8::Module::Status |
|
static |
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.
MaybeLocal< Value > v8::Module::Evaluate | ( | Local< Context > | context | ) |
Evaluates the module and its dependencies.
If status is kInstantiated, run the module's code and return a Promise object. On success, set status to kEvaluated and resolve the Promise with the completion value; on failure, set status to kErrored and reject the Promise with the error.
If IsGraphAsync() is false, the returned Promise is settled.
For a module in kErrored status, this returns the corresponding exception.
int v8::Module::GetIdentityHash | ( | ) | const |
Returns the identity hash for this object.
Returns the namespace object of this module.
The module's status must be at least kInstantiated.
Local< FixedArray > v8::Module::GetModuleRequests | ( | ) | const |
Returns the ModuleRequests for this module.
std::pair< LocalVector< Module >, LocalVector< Message > > v8::Module::GetStalledTopLevelAwaitMessages | ( | Isolate * | isolate | ) |
Search the modules requested directly or indirectly by the module for any top-level await that has not yet resolved. If there is any, the returned pair of vectors (of equal size) contain the unresolved module and corresponding message with the pending top-level await. An embedder may call this before exiting to improve error messages.
Status v8::Module::GetStatus | ( | ) | const |
Returns the module's current status.
Local< UnboundModuleScript > v8::Module::GetUnboundModuleScript | ( | ) |
Returns the corresponding context-unbound module script.
The module must be unevaluated, i.e. its status must not be kEvaluating, kEvaluated or kErrored.
bool v8::Module::HasTopLevelAwait | ( | ) | const |
Returns whether this module is individually asynchronous (for example, if it's a Source Text Module Record containing a top-level await). See [[HasTLA]] in https://tc39.es/ecma262/#sec-cyclic-module-records
Maybe< bool > v8::Module::InstantiateModule | ( | Local< Context > | context, |
ResolveModuleCallback | module_callback, | ||
ResolveSourceCallback | source_callback = nullptr |
||
) |
Instantiates the module and its dependencies.
Returns an empty Maybe<bool> if an exception occurred during instantiation. (In the case where the callback throws an exception, that exception is propagated.)
bool v8::Module::IsGraphAsync | ( | ) | const |
Returns whether this module or any of its requested modules is async, i.e. contains top-level await.
The module's status must be at least kInstantiated.
bool v8::Module::IsSourceTextModule | ( | ) | const |
Returns whether the module is a SourceTextModule.
bool v8::Module::IsSyntheticModule | ( | ) | const |
Returns whether the module is a SyntheticModule.
int v8::Module::ScriptId | ( | ) | const |
Returns the underlying script's id.
The module must be a SourceTextModule and must not have a kErrored status.
Maybe< bool > v8::Module::SetSyntheticModuleExport | ( | Isolate * | isolate, |
Local< String > | export_name, | ||
Local< Value > | export_value | ||
) |
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 CreateSyntheticModule. An error will be thrown if export_name is not one of the export_names that were passed in that CreateSyntheticModule call. Returns Just(true) on success, Nothing<bool>() if an error was thrown.
Location v8::Module::SourceOffsetToLocation | ( | int | offset | ) | const |
For the given source text offset in this module, returns the corresponding Location with line and column numbers.
