Struct Interval 

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

A PostgreSQL interval: an exact count of months and days plus a microsecond time component.

Months and days are kept separate because their length depends on the calendar (a month may be 28–31 days) and they cannot be collapsed into a single duration losslessly.

Fields

months: i32

Number of months.

days: i32

Number of days.

micros: i64

Number of microseconds.

Implementations

impl Interval

pub const fn new(months: i32, days: i32, micros: i64) -> Self

Creates an interval from its components.

Trait Implementations

impl Clone for Interval

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Interval

impl Debug for Interval

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

Formats the value using the given formatter.

impl Default for Interval

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Interval

impl FromRow for Interval

fn from_row(row: &Row) -> Result<Self, Error>

Builds a value from a row.

impl FromSql for Interval

fn from_sql(_oid: Oid, buf: &[u8]) -> Result<Self, Error>

Decodes a non-null value of type oid.

fn accepts(oid: Oid) -> bool

Whether this type can be decoded from a column of type oid.

fn from_sql_zoned(oid: Oid, buf: &[u8], zone: TimeZone) -> Result<Self, Error>

Decodes a non-null value, using zone to interpret zone-less temporal values (timestamp, date, time).

fn from_sql_null() -> Result<Self, Error>

Decodes SQL NULL.

impl Hash for Interval

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

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 PartialEq for Interval

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl RowShape for Interval

const SHAPE: &'static [ColumnSpec]

The columns this type expects.

impl StaticType for Interval

const OID: Oid = INTERVALOID

The PostgreSQL type OID of this Rust type.

const NULLABLE: bool = false

Whether this Rust type can represent SQL NULL (i.e. it is Option).

impl StructuralPartialEq for Interval

impl ToSql for Interval

fn encode(&self, buf: &mut BytesMut) -> Result<IsNull, Error>

Appends the binary representation of this value to buf, without a length prefix.

fn oid(&self) -> Oid

The PostgreSQL type OID of this value.
