Struct JsInstant 

pub struct JsInstant { /* private fields */ }

A monotonic instant in time, in the Boa engine.

This type is guaranteed to be monotonic, i.e. if two instants are compared, the later one will always be greater than the earlier one.

This mirrors the behavior of std::time::Instant and represents a measurement of elapsed time relative to an arbitrary starting point. It is NOT tied to wall-clock time or the Unix epoch, and system clock adjustments will not affect it.

This should not be used to keep dates or times, but only to measure monotonic time progression in the engine.

Implementations

impl JsInstant

pub fn new(secs: u64, nanos: u32) -> Self

Creates a new JsInstant from the given number of seconds and nanoseconds.

pub fn millis_since_epoch(&self) -> u64

Returns the number of milliseconds since the clock’s starting point.

Note: This is NOT a Unix timestamp. It represents elapsed time since an arbitrary starting point and is only meaningful for measuring durations and comparing instants.

pub fn nanos_since_epoch(&self) -> u128

Returns the number of nanoseconds since the clock’s starting point.

Note: This is NOT a Unix timestamp. It represents elapsed time since an arbitrary starting point and is only meaningful for measuring durations and comparing instants.
