Struct mmtk::util::options::MMTKOption
source · pub struct MMTKOption<T: Debug + Clone> {
value: T,
validator: fn(_: &T) -> bool,
from_env_var: bool,
from_command_line: bool,
}
Expand description
An MMTk option of a given type. This type allows us to store some metadata for the option. To get the value of an option, you can simply dereference it (for example, *options.threads).
Fields§
§value: T
The actual value for the option
validator: fn(_: &T) -> bool
The validator to ensure the value is valid.
from_env_var: bool
Can we set this option through env vars?
from_command_line: bool
Can we set this option through command line options/API?
