Struct Months

pub struct Months(/* private fields */);

A duration in calendar months, analog to chrono::Months. Unlike chrono::Months, this type can represent a negative duration.

Implementations

impl Months

pub const fn new(num: i32) -> Self

fn add(self, rhs: Months) -> Self::Output

Performs the + operation.

impl Clone for Months

fn clone(&self) -> Months

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Months

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

Formats the value using the given formatter.

impl<'r> Decode<'r, Exasol> for Months

fn decode(value: ExaValueRef<'r>) -> Result<Self, BoxDynError>

Decode a new value of this type using a raw value from the database.

impl Encode<'_, Exasol> for Months

fn encode_by_ref(&self, buf: &mut ExaBuffer) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

fn produces(&self) -> Option<ExaTypeInfo>

fn size_hint(&self) -> usize

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

impl From<Months> for Months

fn from(value: Months) -> Self

Converts to this type from the input type.

impl Hash for Months

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 PartialEq for Months

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

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

fn sub(self, rhs: Months) -> Self::Output

Performs the - operation.

impl Sub<Months> for NaiveDate

type Output = NaiveDate

The resulting type after applying the - operator.

fn sub(self, rhs: Months) -> Self::Output

Performs the - operation.

impl Sub<Months> for NaiveDateTime

type Output = NaiveDateTime

The resulting type after applying the - operator.

fn sub(self, rhs: Months) -> Self::Output

Performs the - operation.
