RelationalAtom

Enum RelationalAtom 

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

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§

Source§

impl RelationalAtom

Source

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.
