Struct Task 

pub struct Task {

    pub id: String,
    pub name: String,
    pub kind: TaskKind,
    pub effort_hours: f32,
    pub dependencies: Vec<String>,
    pub lag_by_dependency: HashMap<String, f32>,
    pub status: TaskStatus,
    pub earliest_start: f32,
    pub earliest_finish: f32,
    pub latest_start: f32,
    pub latest_finish: f32,
    pub float: f32,
    pub is_critical: bool,
    pub affected_files: Vec<String>,
}

A single task in the CPM plan.

Fields

id: String

Unique identifier.

name: String

Human-readable name.

kind: TaskKind

Type of task.

effort_hours: f32

Scheduled length in hours. For tasks built from a deliverable this is its calendar duration_hours when set, else its effort estimate; earned value reads effort from the graph, not from here.

dependencies: Vec<String>

Task IDs this depends on (must complete before this can start).

lag_by_dependency: HashMap<String, f32>

Minimum wait in hours between a dependency’s finish and this task’s start, keyed by dependency id. Absent means 0.

status: TaskStatus

Current status.

earliest_start: f32

Earliest start time (calculated by forward pass).

earliest_finish: f32

Earliest finish time (ES + effort).

latest_start: f32

Latest start time (calculated by backward pass).

latest_finish: f32

Latest finish time.

float: f32

Float/slack time (LS - ES).

is_critical: bool

Is this task on the critical path?

affected_files: Vec<String>

Files affected by this task (for context building, domain-neutral).

Implementations

impl Task

pub fn new( id: impl Into<String>, name: impl Into<String>, kind: TaskKind, effort_hours: f32, ) -> Self

Create a new task with the given ID, name, kind, and effort.

pub fn depends_on(self, task_id: impl Into<String>) -> Self

Add a dependency to this task.

pub fn affects_file(self, file: impl Into<String>) -> Self

Add an affected file.

Trait Implementations

impl Clone for Task

fn clone(&self) -> Self

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Task

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Task

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Task

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Task

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
