Struct DateTime

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

A type that represents a datetime with subsecond precision.

This type is used throughout the flow trading system to represent timestamps for events, validity periods, and historical records. It ensures:

• All times are stored and processed in UTC
• Serialization/deserialization uses RFC3339 format
• SQLite storage uses the appropriate datetime type

Examples

let now = OffsetDateTime::now_utc();
let datetime = DateTime::from(now);
println!("{}", datetime); // Prints in RFC3339 format

Trait Implementations

impl Clone for DateTime

fn clone(&self) -> DateTime

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DateTime

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

Formats the value using the given formatter.

impl<'r, DB: Database> Decode<'r, DB> for DateTime

where PrimitiveDateTime: Decode<'r, DB>,

fn decode( value: <DB as Database>::ValueRef<'r>, ) -> Result<Self, Box<dyn Error + Send + Sync + 'static>>

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

impl<'de> Deserialize<'de> for DateTime

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DateTime

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

Formats the value using the given formatter.

impl<'q, DB: Database> Encode<'q, DB> for DateTime

where PrimitiveDateTime: Encode<'q, DB>,

fn encode_by_ref( &self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

fn produces(&self) -> Option<DB::TypeInfo>

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<T: Borrow<OffsetDateTime>> From<T> for DateTime

fn from(value: T) -> Self

Converts to this type from the input type.

impl Into<OffsetDateTime> for DateTime

fn into(self) -> OffsetDateTime

Converts this type into the (usually inferred) input type.

impl Ord for DateTime

fn cmp(&self, other: &DateTime) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DateTime

fn eq(&self, other: &DateTime) -> bool

Tests for self and other values to be equal, and is used by ==.

const 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 DateTime

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

impl Serialize for DateTime

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<DB: Database> Type<DB> for DateTime

where PrimitiveDateTime: Type<DB>,

fn type_info() -> DB::TypeInfo

Returns the canonical SQL type for this Rust type.

fn compatible(ty: &DB::TypeInfo) -> bool

Determines if this Rust type is compatible with the given SQL type.

impl Copy for DateTime
