Struct TaskId 

pub struct TaskId(/* private fields */);

A unit of intended work that a person opens and closes: t-<YYYYMMDDHHMMSS>-<4 hex>.

An super::Episode carries Option<TaskId> and nothing else of a task. The separation is ADR 0052’s whole finding: a task is optional, is opened and closed by a person, and outlives or predeceases any number of episodes. What made this repository write no checkpoint and no handover for six days was code that asked a task whether an episode’s artefact should be written.

use majordomus_cli::session::{EpisodeId, TaskId};

let t = TaskId::parse("t-20260905034523-a9f1").expect("the task from the audit");
assert_eq!(t.as_str(), "t-20260905034523-a9f1");

// the shapes rhyme and the types do not: an episode id is not a task id
assert!(TaskId::parse("s-20260910205542-e2a6").is_none());
assert!(EpisodeId::parse("t-20260905034523-a9f1").is_none());

Implementations

impl TaskId

pub fn parse(text: &str) -> Option<Self>

Parse an id as lib/start.sh writes it. None for anything else, including the literal none the records use for “no task”, which is an absence and is represented as Option::None rather than as a task whose name is a word.

use majordomus_cli::session::TaskId;
assert!(TaskId::parse("t-20260905034523-a9f1").is_some());
assert!(TaskId::parse("none").is_none(), "the records' word for no task");

pub fn as_str(&self) -> &str

The id as text: what a record writes as task_id:. An episode relates to a task by this value and holds nothing else of one.

use majordomus_cli::session::TaskId;
let t = TaskId::parse("t-20260905034523-a9f1").expect("a task id");
assert_eq!(t.as_str(), "t-20260905034523-a9f1");

Trait Implementations

impl Clone for TaskId

fn clone(&self) -> TaskId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TaskId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TaskId

impl Hash for TaskId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl JsonSchema for TaskId

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Ord for TaskId

fn cmp(&self, other: &TaskId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TaskId

fn eq(&self, other: &TaskId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for TaskId

fn partial_cmp(&self, other: &TaskId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for TaskId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
