Struct StepMatch 

pub struct StepMatch {
    pub states: Vec<CreditRegistrationState>,
    pub completion_eligible: Vec<bool>,
    pub has_verified_student_number: Vec<bool>,
    pub course_code_allowed: Vec<bool>,
    pub enrolment_resolved: Vec<bool>,
    pub steps: Vec<TimelineStep>,
}

The (state, completion_eligible, has_verified_student_number, course_code_allowed, enrolment_resolved) combinations a set of steps covers, each with its step, as parallel arrays for a query to UNNEST and join against, as a filter or via Self::all.

Enumerated from TimelineStep::of rather than restated as a SQL predicate, so a list filtered by a step returns exactly the rows that show that step.

Fields

states: Vec<CreditRegistrationState>

completion_eligible: Vec<bool>

has_verified_student_number: Vec<bool>

course_code_allowed: Vec<bool>

enrolment_resolved: Vec<bool>

steps: Vec<TimelineStep>

Implementations

impl StepMatch

pub fn of(steps: &[TimelineStep]) -> Self

Empty for an empty steps, which every query reads as “do not narrow”.

pub fn all() -> Self

Every combination, for reading the step of any row.

Trait Implementations

impl Clone for StepMatch

fn clone(&self) -> StepMatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StepMatch

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

Formats the value using the given formatter.

impl Default for StepMatch

fn default() -> StepMatch

Returns the “default value” for a type.

impl PartialEq for StepMatch

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