Struct Interval 

pub struct Interval { /* private fields */ }

An interval value.

Hyper stores intervals as a 128-bit packed value with:

• microseconds (i64): time component
• days (i32): day component
• months (i32): month component

Implementations

impl Interval

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

Creates an Interval from components.

pub const fn from_years(years: i32) -> Interval

Creates an Interval from years.

pub const fn from_months(months: i32) -> Interval

Creates an Interval from months.

pub const fn from_days(days: i32) -> Interval

Creates an Interval from days.

pub const fn from_hours(hours: i64) -> Interval

Creates an Interval from hours.

pub const fn from_minutes(minutes: i64) -> Interval

Creates an Interval from minutes.

pub const fn from_seconds(seconds: i64) -> Interval

Creates an Interval from seconds.

pub const fn from_microseconds(microseconds: i64) -> Interval

Creates an Interval from microseconds.

pub const fn months(&self) -> i32

Returns the months component.

pub const fn days(&self) -> i32

Returns the days component.

pub const fn microseconds(&self) -> i64

Returns the microseconds component.

pub fn encode(&self) -> [u8; 16]

Encodes the interval as a 128-bit value for HyperBinary.

Layout: [microseconds: i64 LE][days: i32 LE][months: i32 LE]

pub fn decode(buf: &[u8; 16]) -> Interval

Decodes an interval from a 128-bit value.

pub fn to_packed(&self) -> [u8; 16]

Returns the packed 128-bit representation for insertion.

This is an alias for encode() for API consistency.

Trait Implementations

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<(), Error>

Formats the value using the given formatter.

impl Display for Interval

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

Formats the value using the given formatter.

impl FromBinaryValue for Interval

fn from_stream_row(row: &StreamRow, idx: usize) -> Option<Interval>

Extracts a value from a StreamRow at the given column index.

fn from_batch_row(row: &BatchRow, idx: usize) -> Option<Interval>

Extracts a value from a BatchRow at the given column index.

impl FromHyperBinary for Interval

fn from_hyper_binary( buf: &[u8], ) -> Result<Interval, Box<dyn Error + Sync + Send>>

Deserializes a value from HyperBinary format.

impl Hash for Interval

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 IntoValue for &Interval

fn add_to_inserter(&self, inserter: &mut Inserter<'_>) -> Result<()>

Adds this value to the inserter.

impl IntoValue for Interval

fn add_to_inserter(&self, inserter: &mut Inserter<'_>) -> Result<()>

Adds this value to the inserter.

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 RowValue for Interval

fn from_row(row: &Row, idx: usize) -> Option<Self>

Extract a value from a Row at the given column index.

impl ToHyperBinary for Interval

fn to_hyper_binary( &self, buf: &mut BytesMut, ) -> Result<(), Box<dyn Error + Sync + Send>>

Serializes the value to HyperBinary format for a nullable column.

fn to_hyper_binary_not_null( &self, buf: &mut BytesMut, ) -> Result<(), Box<dyn Error + Sync + Send>>

Serializes the value to HyperBinary format for a NOT NULL column.

fn hyper_binary_size(&self) -> usize

Returns the size in bytes this value will occupy when serialized (nullable).

fn hyper_binary_size_not_null(&self) -> usize

Returns the size in bytes this value will occupy when serialized (not nullable).
