Struct SystemTimeTime 

pub struct SystemTimeTime;

Time implementation for std::time::SystemTime.

instant_sub panics if a < b because Duration cannot represent negative values. Use Time::instant_cmp to compare instants.

Trait Implementations

impl Time for SystemTimeTime

type Instant = SystemTime

type Duration = Duration

fn instant_sub(a: SystemTime, b: SystemTime) -> Duration

Returns a - b. Behavior when a < b is unspecified: implementations may panic or return a meaningless value. Use instant_cmp to check ordering first if unsure.

fn duration_sub(a: Duration, b: Duration) -> Duration

Returns a - b. Behavior when a < b is unspecified: implementations may panic or return a meaningless value.

fn duration_add(a: Duration, b: Duration) -> Duration

fn mixed_sub(a: SystemTime, b: Duration) -> SystemTime

fn mixed_add(a: SystemTime, b: Duration) -> SystemTime

fn instant_cmp(a: Self::Instant, b: Self::Instant) -> Ordering
