Struct Duration 

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

ROS Duration representation

Matches builtin_interfaces/msg/Duration:

• sec: Seconds (signed for negative durations)
• nanosec: Nanoseconds (0-999999999)

Fields

sec: i32

Seconds component

nanosec: u32

Nanoseconds component (0-999999999)

fn add(self, rhs: Duration) -> <Time as Add<Duration>>::Output

Performs the + operation.

impl Add for Duration

type Output = Duration

The resulting type after applying the + operator.

fn add(self, rhs: Duration) -> <Duration as Add>::Output

Performs the + operation.

impl Clone for Duration

fn clone(&self) -> Duration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Duration

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

Formats the value using the given formatter.

impl Default for Duration

fn default() -> Duration

Returns the “default value” for a type.

impl Deserialize for Duration

fn deserialize(reader: &mut CdrReader<'_>) -> Result<Duration, DeserError>

impl From<Duration> for TimerDuration

fn from(d: Duration) -> TimerDuration

Converts to this type from the input type.

impl From<TimerDuration> for Duration

fn from(d: TimerDuration) -> Duration

Converts to this type from the input type.

impl Ord for Duration

fn cmp(&self, other: &Duration) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Duration

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Duration

fn partial_cmp(&self, other: &Duration) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

fn serialize(&self, writer: &mut CdrWriter<'_>) -> Result<(), SerError>

Serialize this value to the CDR writer

impl Sub<Duration> for Time

type Output = Time

The resulting type after applying the - operator.

fn sub(self, rhs: Duration) -> <Time as Sub<Duration>>::Output

Performs the - operation.

impl Sub for Duration

type Output = Duration

The resulting type after applying the - operator.

fn sub(self, rhs: Duration) -> <Duration as Sub>::Output

Performs the - operation.
