Struct EmbassyTimestampGenerator 

pub struct EmbassyTimestampGenerator { /* private fields */ }

Monotonic timestamp generator backed by embassy_time::Instant.

This type implements NtpTimestampGenerator by capturing the current monotonic time via Instant::now on each call to init, then reporting the elapsed seconds and sub-second microseconds.

It does not provide wall-clock time. Instead, it provides a monotonic timestamp source suitable for SNTP round-trip delay calculations, where only the relative elapsed time between request and response matters.

Example

use sntpc::NtpContext;
use sntpc_time_embassy::EmbassyTimestampGenerator;

let ntp_context = NtpContext::new(EmbassyTimestampGenerator::default());

Trait Implementations

impl Clone for EmbassyTimestampGenerator

fn clone(&self) -> EmbassyTimestampGenerator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for EmbassyTimestampGenerator

fn default() -> Self

Returns a default EmbassyTimestampGenerator with the instant set to the epoch.

The instant is initialized to Instant::from_secs(0) and will be updated to the current time when init is called before each timestamp measurement.

impl NtpTimestampGenerator for EmbassyTimestampGenerator

fn init(&mut self)

Captures the current monotonic time from embassy_time::Instant::now.

This method should be called before each pair of timestamp_sec and timestamp_subsec_micros calls to ensure the timestamp reflects the current moment.

fn timestamp_sec(&self) -> u64

Returns the whole seconds component of the captured monotonic instant.

The value represents seconds elapsed since the Embassy runtime’s monotonic clock epoch, not since the UNIX epoch.

fn timestamp_subsec_micros(&self) -> u32

Returns the sub-second microsecond component of the captured monotonic instant.

This is the fractional part of the timestamp in whole microseconds (i.e., microseconds within the current second, in the range 0..1_000_000).
