[−][src]Struct spirit::validation::Action
A validation action.
The validator (see config_validator
) is
supposed to either return an error or an action to be taken once validation completes.
By default, the Action
is empty, but an on_success
and
on_abort
callbacks can be attached to it. These'll execute once the
validation completes (only one of them will be called, depending on the result of validation).
Examples
use spirit::{Empty, Spirit}; use spirit::prelude::*; use spirit::validation::Action; Spirit::<Empty, Empty>::new() .config_validator(|_old_cfg, new_cfg, _opts| { let something = create_something(new_cfg)?; Ok(Action::new().on_success(move || install_something(something))) });
Or, if you want to only check the configuration:
use spirit::{Empty, Spirit}; use spirit::prelude::*; use spirit::validation::Action; Spirit::<Empty, Empty>::new() .config_validator(|_old_cfg, new_cfg, _opts| { looks_good(new_cfg)?; Ok(Action::new()) });
Implementations
impl Action
[src]
pub fn new() -> Self
[src]

pub fn on_success<F: FnOnce() + 'static>(self, f: F) -> Self
[src]
Attaches (replaces) the success action.
pub fn on_abort<F: FnOnce() + 'static>(self, f: F) -> Self
[src]
Attaches (replaces) the failure action.
