Struct Plan 

pub struct Plan {
    pub steps: Vec<Step>,
    pub current: Option<usize>,
    pub revision: u64,
    pub transitions: Vec<PlanTransition>,
}

Current state and complete history, restored with the service.

Fields

steps: Vec<Step>

Steps in ordinal order.

current: Option<usize>

The sole doing step’s id, or none.

revision: u64

Increases once for each accepted write.

transitions: Vec<PlanTransition>

Every accepted write, oldest first.

Implementations

impl Plan

pub fn validate(&self, limits: &SiteLimits) -> Result<(), SiteError>

Validates the complete stored plan before any retained value is served.

Errors

A configured bound, invalid ordinal, conflicting current or broken history.

pub fn set( &mut self, titles: &[String], holder: &str, at_ms: u64, limits: &SiteLimits, ) -> Result<(), SiteError>

Replaces the list without removing or renaming any finished ordinal.

Errors

A configured bound, invalid title or finished step change.

pub fn step( &mut self, id: usize, status: StepStatus, note: Option<String>, holder: &str, at_ms: u64, limits: &SiteLimits, ) -> Result<(), SiteError>

Changes one step, preserving the single doing step and terminal completion.

Errors

Unknown ordinal, invalid note, another doing step or a configured bound.
