Struct Stamp 

pub struct Stamp(/* private fields */);

One UTC minute: 20261001-0000 on the wire, 2026-10-01 00:00Z to read.

Implementations

impl Stamp

pub fn parse(text: &str) -> Option<Stamp>

Reads YYYYMMDD-HHMM exactly, spaces around it aside. None for any other shape and for a day or minute that does not exist.

pub fn exact(text: &str) -> Option<Stamp>

YYYYMMDD-HHMM and nothing else, not even a space: 20260231-1200, 20261001-2400 and 20261001-1260 are no minute.

pub fn day(text: &str) -> Option<Stamp>

A day as YYYYMMDD and nothing else, at its midnight.

pub const fn from_minutes(minutes: i64) -> Stamp

Minutes since 1970.

pub const fn minutes(self) -> i64

pub const fn ms(self) -> i64

Milliseconds since 1970.

pub fn passed(self, now_ms: u64) -> bool

Whether now_ms is at or past this minute.

pub fn wire(self) -> String

YYYYMMDD-HHMM, as a description writes it.
