Crate planter_core 

This is a library with types and behaviour inspired by the PMBOK Guide 7th edition.

Modules

duration

A duration is a unit of time that represents the amount of time required to complete a task.

money

Monetary values, stored as an integer count of a currency’s minor unit (e.g. cents). Every amount carries its currency; costs come back as a MultiCurrencyAmount that keeps each currency separate rather than silently combining them.

person

A person can either be a resource, a team member or a stakeholder.

project

A project ties everything else in this crate together: tasks (which can nest into subtasks and carry time relationships to each other), the resources they engage, and the project’s stakeholders. It’s the entry point for computing overall cost.

resources

A resource is anything the project pays for. It’s a named, cost-bearing thing with an optional contact; its cost has two independent parts, either of which may be absent: one-time purchases, and an hourly rate charged for the time a task engages it. The crate imposes no taxonomy of what a resource is - that classification is project-specific.

stakeholders

A stakeholder is a person or organization with an interest in the project: either an Individual (with contact details via person::Person) or an Organization (identified by name), each optionally carrying a description of that interest.

task

A task is a unit of work needed to achieve the project’s objectives. It can have a name, a description, a start and finish date, a duration, a completed flag, and resources assigned to it; it can also be nested into subtasks and related to other tasks in time.

title

A human-readable name for a domain entity: trimmed, non-empty, length-capped, but otherwise unrestricted in content.

Structs

Uuid

A Universally Unique Identifier (UUID).
