Struct Time 

pub struct Time { /* private fields */ }

A time value (microseconds since midnight).

Implementations

impl Time

pub const MICROS_PER_SECOND: u64 = 1_000_000

Microseconds per second

pub const MICROS_PER_MINUTE: u64

Microseconds per minute

pub const MICROS_PER_HOUR: u64

Microseconds per hour

pub const MAX_MICROSECONDS: u64

Maximum valid microseconds value (24 hours - 1 microsecond).

pub const fn from_microseconds(microseconds: u64) -> Time

Creates a Time from microseconds since midnight.

No validation is performed. For a checked variant, use try_from_microseconds.

pub fn try_from_microseconds( microseconds: u64, ) -> Result<Time, Box<dyn Error + Sync + Send>>

Creates a Time from microseconds since midnight with validation.

Errors

Returns an error if microseconds > MAX_MICROSECONDS (i.e. >= 24 hours).

pub const fn new(hour: u32, minute: u32, second: u32, microsecond: u32) -> Time

Creates a Time from hour, minute, second, microsecond components.

pub const fn microseconds(&self) -> u64

Returns microseconds since midnight.

pub const fn to_hms_micro(&self) -> (u32, u32, u32, u32)

Returns hour, minute, second, microsecond components.

pub const fn encode(&self) -> u64

Returns the raw encoded value.

pub const fn decode(encoded: u64) -> Time

Creates a Time from a raw encoded value.

pub const fn to_microseconds(&self) -> i64

Returns microseconds since midnight as i64 for insertion.

This is the same as microseconds() but as signed for the Inserter API.

Trait Implementations

impl Clone for Time

fn clone(&self) -> Time

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Time

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

Formats the value using the given formatter.

impl Display for Time

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

Formats the value using the given formatter.

impl From<NaiveTime> for Time

fn from(t: NaiveTime) -> Time

Converts to this type from the input type.

impl FromBinaryValue for Time

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

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

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

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

impl FromHyperBinary for Time

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

Deserializes a value from HyperBinary format.

impl Hash for Time

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 &Time

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

Adds this value to the inserter.

impl IntoValue for Time

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

Adds this value to the inserter.

impl PartialEq for Time

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

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

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

impl ToHyperBinary for Time

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).

impl ToSqlParam for Time

fn encode_param(&self) -> Option<Vec<u8>>

Encodes this value as binary bytes for use in parameterized queries.

fn sql_oid(&self) -> Oid

Returns the SQL type OID this parameter should bind as.

fn to_sql_literal(&self) -> String

Returns the SQL literal representation of this value.
