Struct Decisions 

pub struct Decisions {
    pub tasks: BTreeMap<String, TaskDecisions>,
}

All decisions, by feature/task.

Fields

tasks: BTreeMap<String, TaskDecisions>

By feature/task.

Implementations

impl Decisions

pub fn load(dir: &Path) -> Result<Self, String>

Reads the decisions in dir; none when there is no file yet. A file in an earlier shape (grants by class, not object) is an error naming it: reading it as “no decisions” would drop its rejections.

pub fn save(&self, dir: &Path) -> Result<(), String>

Writes the decisions to dir (temporary file, then rename).

pub fn for_task(&self, feature: &str, task: &str) -> TaskDecisions

The decisions for feature/task.

pub fn for_run(&self, feature: &str, task: &str, run: &str) -> Vec<Object>

The objects approved for feature/task in run: never another run’s (a grant ends with its run).

pub fn take_once(&mut self, feature: &str, task: &str, run: &str) -> Vec<Object>

Removes and returns the once-grants of feature/task claimed by run: the attempt they are handed to may make each call one time, and no later attempt has them.

pub fn approve_once( &mut self, feature: &str, task: &str, object: Object, by: &Who, )

Records an approval of object for one call of the task’s next attempt (a call a lane stopped, decided in its run’s batch); a rejection of the same object is withdrawn.

pub fn claim(&mut self, feature: &str, task: &str, run: &str) -> bool

Binds the task’s unclaimed grants (decisions on a call a lane stopped) to run, the run that now attempts it; whether any was.

pub fn approve( &mut self, feature: &str, task: &str, object: Object, run: Option<&str>, by: &Who, )

Records an approval of object in run; a rejection of the same object is withdrawn.

pub fn note(&mut self, feature: &str, task: &str, decided: Decided)

Records a decision that changes nothing for the task (an inline approval or rejection of one call): the history only.

pub fn reject( &mut self, feature: &str, task: &str, object: Object, reason: &str, by: &Who, )

Records a rejection; an approval of the same object is withdrawn.

pub fn decided(&self, feature: &str, task: &str, object: &Object) -> bool

Whether object was decided for feature/task either way. An earlier run’s grant does not count: it covers nothing now.
