Implementations

impl DatePeriod

pub fn new(range_type: &str) -> Result<Self>

Create a new DatePeriod from a string representation.

• Accepts “YEAR”, “Y”, “QUARTER”, “Q”, “MONTH”, “M”, “DAILY”, “D” (case insensitive).
• Returns an error for invalid inputs.

Examples

use range_date::range_type::DatePeriod;

let dp = DatePeriod::new("Y").unwrap();
assert_eq!(dp, DatePeriod::Year);
let dp = DatePeriod::new("MONTH").unwrap();
assert_eq!(dp, DatePeriod::Month);
let dp = DatePeriod::new("invalid");
assert!(dp.is_err());

Performs copy-assignment from source.

impl Debug for DatePeriod

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DatePeriod

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DatePeriod

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

Formats the value using the given formatter.

impl FromStr for DatePeriod

type Err = Error

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 Hash for DatePeriod

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 DatePeriod

fn cmp(&self, other: &DatePeriod) -> 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 DatePeriod

fn eq(&self, other: &DatePeriod) -> 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 DatePeriod

fn partial_cmp(&self, other: &DatePeriod) -> 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 Serialize for DatePeriod

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
