Implementations

impl DateTruncGranularity

const SUPPORTED_GRANULARITIES: &[&str]

List of all supported granularity values Cannot use HashMap here as it would require lazy_static or once_cell, Rust does not support const HashMap yet.

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

Parse a granularity string into a DateTruncGranularity enum

fn is_fine_granularity(&self) -> bool

Returns true if this granularity can be handled with simple arithmetic (fine granularity: second, minute, millisecond, microsecond)

fn is_fine_granularity_utc(&self) -> bool

Returns true if this granularity can be handled with simple arithmetic in UTC (hour and day in addition to fine granularities)

Trait Implementations

impl Clone for DateTruncGranularity

fn clone(&self) -> DateTruncGranularity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DateTruncGranularity

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

Formats the value using the given formatter.

impl PartialEq for DateTruncGranularity

fn eq(&self, other: &DateTruncGranularity) -> 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.
