KeiraClock

lilkaoxide::keira_rtc

Struct KeiraClock 

Source 
pub struct KeiraClock { /* private fields */ }
Expand description

A UTC clock sampled from RTC, then advanced by the monotonic HAL timer.

Values are checked against 2020-01-01..2108-01-01 (exclusive upper bound). This rejects an unset clock and obvious garbage; it is not proof of accuracy. Dropping this handle does not reset RTC. No timezone conversion is performed.

Implementations§

Source§

impl KeiraClock

Source

pub fn inherit(rtc: &Rtc<'_>) -> Result<Self, RtcTimeError>

Capture the RTC time after crate::Lilka::init.

Only borrows rtc while sampling. The handle need not stay alive later. Returns RtcTimeError::NotSynchronized for an implausible RTC date.

Source

pub fn now_unix_micros(&self) -> Result<u64, RtcTimeError>

Current UTC Unix timestamp in microseconds, without heap allocations.

Source

pub fn now_unix_seconds(&self) -> Result<u64, RtcTimeError>

Current UTC Unix timestamp in whole seconds (fraction truncated).
