Struct MyDuration

pub struct MyDuration(/* private fields */);

Implementation of time duration that wraps Duration to better satisfy the requirements of the xAPI specifications.

Specifically, this implementation considers the patterns [PnnW] and [PnnYnnMnnDTnnHnnMnnS] as valid.

Implementations

impl MyDuration

pub fn new( positive: bool, day: u32, second: u32, microsecond: u32, ) -> Result<Self, DataError>

Construct a new instance from given parameters.

pub fn truncate(&self) -> Self

Return a clone of this excluding precisions beyond 0.01 second.

Needed b/c 4.2.7 Additional Requirements for Data Types / Duration states:

When making a comparison (e.g. as a part of the statement signing process) of Statements in regard to a Duration, any precision beyond 0.01 second precision shall not be included in the comparison.

pub fn positive(&self) -> bool

Return the positive or negative sign of this.

pub fn day(&self) -> u32

Return the number of days in this.

pub fn second(&self) -> u32

Return the number of seconds, range 0 to 86399, in this.

pub fn microsecond(&self) -> u32

Return the number of microseconds, range 0 to 999999, in this.

pub fn to_iso8601(&self) -> String

Return this in ISO8601 format; i.e. “P9DT9H9M9.99S”

Trait Implementations

impl Clone for MyDuration

fn clone(&self) -> MyDuration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MyDuration

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MyDuration

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MyDuration

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

Formats the value using the given formatter.

impl Fingerprint for MyDuration

fn fingerprint<H: Hasher>(&self, state: &mut H)

Feed this value into the given Hasher.

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

where Self: Sized,

Feeds a slice of this type into the given Hasher.

impl FromStr for MyDuration

type Err = DataError

The associated error which can be returned from parsing.

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

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

impl PartialEq for MyDuration

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

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

const 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 Serialize for MyDuration

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
