Struct At 

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

An instant: milliseconds since 1970 in UTC. Read from RFC 3339 and written as RFC 3339 with milliseconds and a Z (2026-09-01T10:00:00.000Z), a fixed width that sorts as text.

Implementations

impl At

pub const fn from_ms(ms: i64) -> At

pub const fn ms(self) -> i64

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

YYYY-MM-DDTHH:MM:SS, a fraction of a second if any (cut to the millisecond), and Z or an offset +HH:MM. A space or a lowercase t may stand for the T, as RFC 3339 allows. None for anything else, a day that does not exist included.

pub const fn plus_days(self, days: i64) -> At

days whole days on, or back when negative.

pub fn plus_months(self, months: i64) -> At

months calendar months on, or back, at the same time of day. A day the month does not have becomes its last: the 31st of January a month on is the 28th of February, or the 29th in a leap year.

pub fn date(self) -> String

The day, YYYY-MM-DD.

pub fn compact(self) -> String

The day, YYYYMMDD, as Hyperliquid names a builder’s day file.
