Struct Duration

pub struct Duration { /* private fields */ }

A span of time.

Precision: microseconds.

assert_eq!(&Duration::from_micros(1_000_000).to_string(), "0:00:01");

This type implements FromStr and parses either seconds or PostgreSQL simple duration format:

assert_eq!(&Duration::from_str("65").unwrap().to_string(), "0:01:05");
assert_eq!(&Duration::from_str("2:12:7.65432").unwrap().to_string(), "2:12:07.65432");

Trait Implementations

impl Clone for Duration

fn clone(&self) -> Duration

Returns a copy 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

Formats the value using the given formatter.

impl Display for Duration

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

Formats the value using the given formatter.

impl From<Duration> for Value

fn from(v: Duration) -> Value

Converts to this type from the input type.

impl FromStr for Duration

type Err = ParseDurationError

The associated error which can be returned from parsing.

fn from_str(input: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Duration

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.

impl ScalarArg for Duration

fn encode(&self, encoder: &mut Encoder<'_>) -> Result<(), Error>

fn check_descriptor( ctx: &DescriptorContext<'_>, pos: TypePos, ) -> Result<(), Error>

fn to_value(&self) -> Result<Value, Error>

impl TryFrom<&Duration> for Duration

The type returned in the event of a conversion error.

fn try_from(value: Duration) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Duration> for Duration

type Error = OutOfRangeError
