Struct Duration 

pub struct Duration {
    pub sec: i32,
    pub nanosec: u32,
}

Duration_t — a relative time span (can be negative when sec < 0).

Fields

sec: i32

Seconds.

nanosec: u32

Nanoseconds-Anteil [0, 999_999_999].

Implementations

impl Duration

pub const ZERO: Self

DURATION_ZERO (spec): 0 seconds.

pub const INFINITE: Self

DURATION_INFINITE (spec): symbolic maximum.

pub const fn new(sec: i32, nanosec: u32) -> Self

Constructor.

pub const fn is_infinite(&self) -> bool

true if the value is Self::INFINITE.

pub const fn is_zero(&self) -> bool

true if the value is Self::ZERO.

pub fn to_core(self) -> Duration

Conversion into core::time::Duration. INFINITE maps to Duration::MAX; negative seconds map to ZERO (core::time::Duration is unsigned).

pub fn from_core(d: Duration) -> Self

Conversion from core::time::Duration (lossy, clamps seconds to i32::MAX).

pub const fn seconds(&self) -> i32

Spec §7.5.6.1 — seconds-Accessor (DDS-PSM-Cxx Duration::seconds()).

pub const fn nanoseconds(&self) -> u32

Spec §7.5.6.1 — nanoseconds-Accessor.

pub fn add_duration(self, d: Duration) -> Self

Spec §7.5.6.4 — Duration + Duration (increment).

pub const fn from_millis(ms: i64) -> Self

Spec §7.5.6.5 — Duration from a millisecond integer.

pub const fn as_millis(&self) -> i64

Spec §7.5.6.5 — Duration as a millisecond integer.
