Enum mapped_command::EnvChange

pub enum EnvChange {
    Remove,
    Set(OsString),
    Inherit,
}

Used to determine how a env variable should be updated.

Variants

Remove

Remove the env value if it normally would have been set

(e.g. because of inherited environment)

Set(OsString)

Make sure the env variable will have given value in the sub-process.

Inherit

Make sure the env variable is inherited from the process spawning the sub-process.

If environment inheritance is disabled (e.g. using with_inherit_env(false)) this will cause given values to still be inherited anyway.

If environment inheritance is enabled this won't have any effect.
