Implementations

impl Interval

pub fn from_duration(duration: Duration) -> Option<Interval>

Tries to convert from the Duration type to a Interval. Will return None on a overflow. This is a lossy conversion in that any units smaller than a microsecond will be lost.

impl Interval

pub fn from_iso(iso_str: &str) -> Result<Interval, ParseError>

impl Interval

pub fn from_postgres(iso_str: &str) -> Result<Interval, ParseError>

impl Interval

pub fn new(months: i32, days: i32, microseconds: i64) -> Interval

Create a new instance of interval from the months, days, and microseconds.

pub fn to_iso_8601(&self) -> String

Output the interval as iso 8601 compliant string.

pub fn to_postgres(&self) -> String

Output the interval as a postgres interval string.

pub fn to_sql(&self) -> String

Output the interval as a sql compliant interval string.

impl Interval

pub fn checked_add(self, other_interval: Interval) -> Option<Interval>

Checked interval addition. Computes Interval + Interval and None if there was an overflow.

pub fn add_day_time( self, days: i32, hours: i64, minutes: i64, seconds: f64, ) -> Interval

Shortcut method to add day time part to the interval. Any units smaller than a microsecond will be truncated.

pub fn checked_add_day_time( self, days: i32, hours: i64, minutes: i64, seconds: f64, ) -> Option<Interval>

Checked day time interval addition. Computes the interval and will return None if a overflow has occured. Any units smaller than a microsecond will be truncated.

pub fn add_year_month(self, year: i32, months: i32) -> Interval

Adds a year month interval.

pub fn checked_add_year_month(self, year: i32, months: i32) -> Option<Interval>

Checked year month addition. Computes the interval and will return None if a overflow has occured.

impl Interval

pub fn checked_sub(self, other_interval: Interval) -> Option<Interval>

Checked interval subtraction. Computes Interval - Interval and None if there was an underflow.

pub fn sub_day_time( self, days: i32, hours: i64, minutes: i64, seconds: f64, ) -> Interval

Shortcut method to subtract day time part to the interval. Any units smaller than a microsecond will be truncated.

pub fn checked_sub_day_time( self, days: i32, hours: i64, minutes: i64, seconds: f64, ) -> Option<Interval>

Checked day time subtraction. Computes the interval and will return None if a overflow/underflow has occured. Any units smaller than a microsecond will be truncated.

pub fn sub_year_month(self, year: i32, months: i32) -> Interval

Subtracts a year month interval.

pub fn checked_sub_year_month(self, year: i32, months: i32) -> Option<Interval>

Checked year month subtraction. Computes the interval and will return None if a overflow has occured.

Trait Implementations

impl Add for Interval

type Output = Interval

The resulting type after applying the + operator.

fn add(self, other_interval: Interval) -> Interval

Performs the + operation.

impl Clone for Interval

fn clone(&self) -> Interval

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Interval

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

Formats the value using the given formatter.

impl<'a> FromSql<'a> for Interval

fn from_sql( _: &Type, raw: &'a [u8], ) -> Result<Self, Box<dyn Error + Sync + Send>>

Creates a new value of this type from a buffer of data of the specified Postgres Type in its binary format.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be created from the specified Postgres Type.

fn from_sql_null(ty: &Type) -> Result<Self, Box<dyn Error + Sync + Send>>

Creates a new value of this type from a NULL SQL value.

fn from_sql_nullable( ty: &Type, raw: Option<&'a [u8]>, ) -> Result<Self, Box<dyn Error + Sync + Send>>

A convenience function that delegates to from_sql and from_sql_null depending on the value of raw.

impl PartialEq for Interval

fn eq(&self, other: &Interval) -> 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 Sub for Interval

type Output = Interval

The resulting type after applying the - operator.

fn sub(self, other_interval: Interval) -> Interval

Performs the - operation.

impl ToSql for Interval

fn to_sql( &self, _: &Type, out: &mut BytesMut, ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

Converts the value of self into the binary format of the specified Postgres Type, appending it to out.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be converted to the specified Postgres Type.

fn to_sql_checked( &self, ty: &Type, out: &mut BytesMut, ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

An adaptor method used internally by Rust-Postgres.

fn encode_format(&self, _ty: &Type) -> Format

Specify the encode format
