Struct MonthSpan 

pub struct MonthSpan {
    pub start: String,
    pub end: String,
}

An inclusive range of months, e.g. MonthSpan::new("2025-01", "2025-09")?.

Pass it anywhere a month argument is accepted to expand to every month in the range (inclusive of both endpoints).

Fields

start: String

First month in the span, inclusive.

end: String

Last month in the span, inclusive.

Implementations

impl MonthSpan

pub fn new( start: impl Into<String>, end: impl Into<String>, ) -> Result<Self, TesseraError>

Create a span, validating both months and their ordering.

Errors

Returns TesseraError::InvalidArgument when either endpoint is not YYYY-MM, or when start is after end.

pub fn months(&self) -> Vec<String>

Return the months in the span as a list of YYYY-MM strings.

Trait Implementations

impl Clone for MonthSpan

fn clone(&self) -> MonthSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MonthSpan

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

Formats the value using the given formatter.

impl Eq for MonthSpan

impl IntoIterator for MonthSpan

fn into_iter(self) -> Self::IntoIter

Iterate the span’s months (inclusive, crossing year boundaries).

type Item = String

The type of the elements being iterated over.

type IntoIter = IntoIter<String>

Which kind of iterator are we turning this into?

impl IntoMonths for MonthSpan

fn into_months(self) -> Result<Vec<String>, TesseraError>

Coerce into a non-empty, validated list of YYYY-MM strings.

impl PartialEq for MonthSpan

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