Fields

castsource: SmolStr

oid (references pg_type.oid) OID of the source data type

casttarget: SmolStr

oid (references pg_type.oid) OID of the target data type

castfunc: Option<SmolStr>

oid (references pg_proc.oid) The OID of the function to use to perform this cast. Zero is stored if the cast method doesn’t require a function.

castcontext: PgCastCastcontext

char Indicates what contexts the cast can be invoked in. e means only as an explicit cast (using CAST or :: syntax). a means implicitly in assignment to a target column, as well as explicitly. i means implicitly in expressions, as well as the other cases.

castmethod: PgCastCastmethod

char Indicates how the cast is performed. f means that the function specified in the castfunc field is used. i means that the input/output functions are used. b means that the types are binary-coercible, thus no conversion is required.

Trait Implementations

impl Clone for PgCast

fn clone(&self) -> PgCast

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PgCast

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PgCast

fn deserialize<__D>( __deserializer: __D, ) -> Result<PgCast, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PgCast

fn eq(&self, other: &PgCast) -> 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 Serialize for PgCast

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for PgCast

impl StructuralPartialEq for PgCast
