Implementations

impl Unit

const fn is_date_unit(self) -> bool

Whether the unit is a valid date unit.

const fn is_time_unit(self) -> bool

Whether the unit is a valid time unit.

const fn is_timestamp_unit(self) -> bool

Whether the unit is a valid timestamp unit.

const fn is_timestamptz_unit(self) -> bool

Whether the unit is a valid timestamptz unit.

const fn is_timestamptz_at_timezone_unit(self) -> bool

Whether the unit is a valid timestamptz at timezone unit.

const fn is_interval_unit(self) -> bool

Whether the unit is a valid interval unit.

fn ensure_date(self) -> Result<Self>

Ensure the unit is a valid date unit.

fn ensure_time(self) -> Result<Self>

Ensure the unit is a valid time unit.

fn ensure_timestamp(self) -> Result<Self>

Ensure the unit is a valid timestamp unit.

fn ensure_timestamptz(self) -> Result<Self>

Ensure the unit is a valid timestamptz unit.

fn ensure_timestamptz_at_timezone(self) -> Result<Self>

Ensure the unit is a valid timestamptz unit.

fn ensure_interval(self) -> Result<Self>

Ensure the unit is a valid interval unit.

Trait Implementations

impl Clone for Unit

fn clone(&self) -> Unit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Unit

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

Formats the value using the given formatter.

impl FromStr for Unit

type Err = ExprError

The associated error which can be returned from parsing.

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

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

impl PartialEq for Unit

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