Struct Interval

pub struct Interval {
    pub months: i32,
    pub days: i32,
    pub microseconds: i64,
}

A type that mimics sqlx::postgres::types::PgInterval but provides both serde::Serialize and serde::Deserialize into and from ISO 8601 string format.

ISO 8601 Duration Format: P(n)Y(n)M(n)DT(n)H(n)M(n)S Where: P - “period”/duration designator (always present at beginning) (n) - integer Y - follows number of years M - follows number of months W - follows number of weeks D - follows number of days T - designator that precedes time components H - follows number of hours M - follows number of minutes S - follows number of seconds

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

Formats the value using the given formatter.

impl<'de> Decode<'de, Postgres> for Interval

fn decode(value: PgValueRef<'de>) -> Result<Self, BoxDynError>

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

impl<'de> Deserialize<'de> for Interval

fn deserialize<D>(deserializer: D) -> Result<Interval, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode<'_, Postgres> for Interval

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

Writes the value of self into buf without moving self.

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.

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

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 PgHasArrayType for Interval

fn array_type_info() -> PgTypeInfo

fn array_compatible(ty: &PgTypeInfo) -> bool

impl Serialize for Interval

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<Duration> for Interval

fn try_from(value: Duration) -> Result<Self, BoxDynError>

Convert a std::time::Duration to a PgInterval

This returns an error if there is a loss of precision using nanoseconds or if there is a microsecond overflow.

type Error = Box<dyn Error + Send + Sync>

The type returned in the event of a conversion error.

impl Type<Postgres> for Interval

fn type_info() -> PgTypeInfo

Returns the canonical SQL type for this Rust type.

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

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

impl Eq for Interval

impl StructuralPartialEq for Interval
