The configurable settings that should be used by the Koto runtime

Fields

run_import_tests: bool

Whether or not tests should be run when importing modules

execution_limit: Option<Duration>

An optional duration that limits how long execution is allowed to take.

If the limit is reached without execution ending, then a Timeout error will be returned.

The VM will check against the execution deadline periodically, with an interval of roughly one tenth of the overall limit’s duration.

The check is performed between VM instructions, so external functions will still be able to block execution.

module_imported_callback: Option<Box<dyn ModuleImportedCallback>>

An optional callback that is called whenever a module is imported by the runtime

This allows you to track the runtime’s dependencies, which might be useful if you want to reload the script when one of its dependencies has changed.

stdin: Ptr<dyn KotoFile>

The runtime’s stdin

stdout: Ptr<dyn KotoFile>

The runtime’s stdout

stderr: Ptr<dyn KotoFile>

The runtime’s stderr
