Enum RelationalAtom 

pub enum RelationalAtom {
    Name(TaskName),
    Project(ProjectName),
    Tag(TagName),
}

A typed relational atom per QRY-004.

Each variant carries the validated identifier that the atom’s predicate compares against. The relational filter flag (--child-of etc.) decides whether the relation walked is direct or transitive.

Variants

Name(TaskName)

name:<TaskName>: the target task’s name equals the given identifier.

Project(ProjectName)

project:<ProjectName>: the target task’s owning project name equals the given identifier.

Tag(TagName)

tag:<TagName>: the target task’s owning project carries the given tag.

Implementations

impl RelationalAtom

pub fn matches( &self, project_name: &ProjectName, task_name: &TaskName, project_tags: &BTreeSet<TagName>, ) -> bool

Evaluate this atom against a candidate target task per QRY-004.

task_name is the task’s own name; project_name is the task’s owning project; project_tags is the project’s tags: set. Returns true iff the atom’s predicate matches the task.

Trait Implementations

impl Clone for RelationalAtom

fn clone(&self) -> RelationalAtom

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelationalAtom

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

Formats the value using the given formatter.

impl Hash for RelationalAtom

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 PartialEq for RelationalAtom

fn eq(&self, other: &RelationalAtom) -> 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.
