Struct FastComponents 

pub struct FastComponents { /* private fields */ }

Fast, stack-allocated date/time components

This is the optimized replacement for HashMap-based ParsedComponents. Total size: 10 * 4 (values) + 2 (known) + 2 (implied) = 44 bytes

Implementations

impl FastComponents

pub const fn new() -> Self

Create new empty components

pub fn with_defaults(reference: &ReferenceWithTimezone) -> Self

Create components with default implied values from a reference date

pub fn is_certain(&self, comp: Component) -> bool

Check if a component is certain (known)

pub fn has(&self, comp: Component) -> bool

Check if a component has any value (known or implied)

pub fn get(&self, comp: Component) -> Option<i32>

Get a component value (known or implied)

pub fn assign(&mut self, comp: Component, value: i32) -> &mut Self

Assign a value to a component (makes it certain/known)

pub fn imply(&mut self, comp: Component, value: i32) -> &mut Self

Imply a value for a component (only if not already known)

pub fn delete(&mut self, comp: Component) -> &mut Self

Delete a component (remove from both known and implied)

pub fn is_only_date(&self) -> bool

Check if only date components are certain (no time)

pub fn is_only_time(&self) -> bool

Check if only time components are certain (no date)

pub fn is_only_weekday_component(&self) -> bool

Check if only weekday is certain

pub fn is_date_with_unknown_year(&self) -> bool

Check if date has unknown year

pub fn get_certain_components(&self) -> Vec<Component>

Get all certain components as a list

pub fn is_valid_date(&self) -> bool

Check if the date components are valid

pub fn to_datetime( &self, reference: &ReferenceWithTimezone, ) -> Option<DateTime<Local>>

Convert to a chrono DateTime
