Struct ros_message::Time

pub struct Time {
    pub sec: u32,
    pub nsec: u32,
}

Fields

sec: u32

Implementations

impl Time

pub fn new() -> Time

Creates a new time of zero value.

Examples

assert_eq!(Time::new(), Time { sec: 0, nsec: 0 });

pub fn from_nanos(t: i64) -> Time

Creates a time of the given number of nanoseconds.

Examples

assert_eq!(Time::from_nanos(0), Time { sec: 0, nsec: 0 });
assert_eq!(Time::from_nanos(12_000_000_123), Time { sec: 12, nsec: 123 });

pub fn from_seconds(sec: u32) -> Time

Creates a time of the given number of seconds.

Examples

assert_eq!(Time::from_seconds(0), Time { sec: 0, nsec: 0 });
assert_eq!(Time::from_seconds(12), Time { sec: 12, nsec: 0 });

pub fn nanos(self) -> i64

Returns the number of nanoseconds in the time.

Examples

assert_eq!(Time { sec: 0, nsec: 0 }.nanos(), 0);
assert_eq!(Time { sec: 12, nsec: 123 }.nanos(), 12_000_000_123);

pub fn seconds(self) -> f64

Returns the number of seconds in the time.

Examples

assert_eq!(Time { sec: 0, nsec: 0 }.seconds(), 0.0);
assert_eq!(Time { sec: 12, nsec: 123 }.seconds(), 12.000_000_123);
