Struct time_util::Transform

pub struct Transform {
    pub monotonic_offset: i64,
    pub synthetic_offset: i64,
    pub rate_adjust_ppm: i32,
    pub error_bound_at_offset: u64,
    pub error_bound_growth_ppm: u32,
}

A transformation from monotonic time to synthetic time, including an error bound on this synthetic time.

Fields

monotonic_offset: i64

An offset on the monotonic timeline in nanoseconds.

synthetic_offset: i64

An offset on the synthetic timeline in nanoseconds.

rate_adjust_ppm: i32

An adjustment to the standard 1 monotonic tick:1 synthetic tick rate in parts per million. Positive values indicate the synthetic clock is moving faster than the monotonic clock.

error_bound_at_offset: u64

The error bound on synthetic clock at monotonic = monotonic_offset.

error_bound_growth_ppm: u32

The growth in error bound per monotonic tick in parts per million.

Implementations

impl Transform

pub fn synthetic(&self, monotonic: Time) -> Time

Returns the synthetic time at the supplied monotonic time.

pub fn error_bound(&self, monotonic: Time) -> u64

Returns the error bound at the supplied monotonic time.

pub fn difference(&self, other: &Transform, monotonic: Time) -> Duration

Returns the synthetic time on this Transform minus the synthetic time on other, calculated at the supplied monotonic time.

pub fn jump_to(&self, monotonic: Time) -> ClockUpdate

Returns a ClockUpdate that will set a Clock onto this Transform using data from the supplied monotonic time.

Trait Implementations

impl Clone for Transform

fn clone(&self) -> Transform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Transform

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Transform

fn default() -> Transform

Returns the “default value” for a type.

impl From<&Clock> for Transform

fn from(clock: &Clock) -> Self

Converts to this type from the input type.

impl PartialEq for Transform

fn eq(&self, other: &Transform) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
