WHITESPACE

Whitespace or tab

date_expression

• Examples: “next Monday”, “tomorrow at 3:00 PM”, “in 2 days”

relative_day_and_specific_time

Parses relative day expressions combined with specific times, such as “tomorrow at 4:00 PM”.

relative_date

Parses expressions for relative dates, for example, “next Tuesday” or “last Friday”.

relative_term

Parses terms representing days relative to today, including “tomorrow”, “today”, and “yesterday”.

specific_day_and_time

Parses expressions that specify both a day and a time, for example, “Wednesday at 5:00 AM”.

specific_day

Parses specific days of the week, with case-insensitive options.

specific_time

Parses a specific time expression, including hour, minute, and AM/PM notation.

future_time

Parses future time expressions, such as “in 3 days” or “in 2 weeks”.

next_or_last

Matches relative terms for dates, allowing “next”, “last”, and “this” qualifiers.

hour

Parses a valid hour value as a sequence of digits.

minute

Parses a valid minute value as a sequence of digits.

am_pm

Parses AM/PM markers, with case-insensitive options.

number

Implementations

impl Rule

pub fn all_rules() -> &'static [Rule]

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rule

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

Formats the value using the given formatter.

impl Hash for Rule

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 Rule

fn cmp(&self, other: &Rule) -> 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 Parser<Rule> for DateParser

fn parse<'i>(rule: Rule, input: &'i str) -> Result<Pairs<'i, Rule>, Error<Rule>>

Parses a &str starting from rule.

impl PartialEq for Rule

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

fn partial_cmp(&self, other: &Rule) -> 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.
