Struct service_install::install::Spec

pub struct Spec<Path, Name, TriggerSet, InstallType>
where
    Path: ToAssign,
    Name: ToAssign,
    TriggerSet: ToAssign,
    InstallType: ToAssign,
{ /* private fields */ }

The configuration for the current install, needed to perform the installation or remove an existing one. Create this by using the install_system or install_user macros.

Implementations

impl<Path, Name, TriggerSet> Spec<Path, Name, TriggerSet, SystemInstall>

where Path: ToAssign, Name: ToAssign, TriggerSet: ToAssign,

pub fn run_as(self, user: impl Into<String>) -> Self

Only available for install_system

impl<Path, Name, TriggerSet, InstallType> Spec<Path, Name, TriggerSet, InstallType>

where Path: ToAssign, Name: ToAssign, TriggerSet: ToAssign, InstallType: ToAssign,

pub fn path( self, path: impl Into<PathBuf> ) -> Spec<Set, Name, TriggerSet, InstallType>

pub fn current_exe( self ) -> Result<Spec<Set, Name, TriggerSet, InstallType>, Error>

Install a copy of the currently running exe.

Errors

Will return an error if the path to the current executable could not be gotten. This can fail for a number of reasons such as filesystem operations and syscall failures.

pub fn name( self, name: impl Display ) -> Spec<Path, Set, TriggerSet, InstallType>

pub fn on_schedule( self, schedule: Schedule ) -> Spec<Path, Name, Set, InstallType>

pub fn on_boot(self) -> Spec<Path, Name, Set, InstallType>

pub fn description(self, description: impl Display) -> Self

pub fn args(self, args: Vec<String>) -> Self

These args will be shell escaped

pub fn working_dir(self, dir: PathBuf) -> Self

pub fn allowed_inits(self, allowed: impl AsRef<[System]>) -> Self

By default all supported init systems will be tried Can be set multiple times to try multiple init systems in the order in which this was set.

Note: setting this for an uninstall might cause it to fail

impl<T: ToAssign> Spec<Set, Set, Set, T>

pub fn prepare_install(self) -> Result<InstallSteps, InstallError>

Prepare for installing. This makes a number of checks and if they are passed it returns the InstallSteps. These implement IntoIterator and can be inspected and executated one by one or executed in one step using InstallSteps::install.

Errors

Returns an error if:

• the install is set to be system wide install while not running as admin/superuser
• the service should run as another user then the current one while not running as admin/superuser
• the service should run for a nonexisting user
• no suitable install directory could be found
• the path for the executable does not point to a file

impl<P: ToAssign, T: ToAssign, I: ToAssign> Spec<P, Set, T, I>

pub fn prepare_remove(self) -> Result<RemoveSteps, RemoveError>

Prepare for removing an install. This makes a number of checks and if they are passed it returns the RemoveSteps. These implement IntoIterator and can be inspected and executated one by one or executed in one step using RemoveSteps::remove.

Errors

Returns an error if:

• trying to remove a system install while not running as admin/superuser
• no install is found
• anything goes wrong setting up the removal

where Path: ToAssign + Debug, Name: ToAssign + Debug, TriggerSet: ToAssign + Debug, InstallType: ToAssign + Debug,
