Struct VariadicArray

pub struct VariadicArray<'mcx, T>(/* private fields */);

Implementations

impl<'mcx, T: UnboxDatum> VariadicArray<'mcx, T>

pub fn iter(&self) -> ArrayIterator<'_, T>

Return an Iterator of Option<T> over the contained Datums.

pub fn iter_deny_null(&self) -> ArrayTypedIterator<'_, T>

Return an iterator over the Array’s elements.

Panics

This function will panic when called if the array contains any SQL NULL values.

pub fn get<'arr>( &'arr self, i: usize, ) -> Option<Option<<T as UnboxDatum>::As<'arr>>>

impl<T> VariadicArray<'_, T>

pub fn into_array_type(self) -> *const ArrayType

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Trait Implementations

impl<'fcx, T> ArgAbi<'fcx> for VariadicArray<'fcx, T>

where T: ArgAbi<'fcx> + UnboxDatum,

unsafe fn unbox_arg_unchecked(arg: Arg<'_, 'fcx>) -> Self

Unbox an argument with a matching type.

unsafe fn unbox_nullable_arg(arg: Arg<'_, 'fcx>) -> Nullable<Self>

Unbox a nullable arg

fn is_virtual_arg() -> bool

“Is this a virtual arg?”

impl<'a, T: FromDatum + UnboxDatum> FromDatum for VariadicArray<'a, T>

unsafe fn from_polymorphic_datum( datum: Datum, is_null: bool, oid: Oid, ) -> Option<VariadicArray<'a, T>>

Like from_datum for instantiating polymorphic types which require preserving the dynamic type metadata.

const GET_TYPOID: bool = false

Should a type OID be fetched when calling from_datum?

unsafe fn from_datum(datum: Datum, is_null: bool) -> Option<Self>

Safety

unsafe fn from_datum_in_memory_context( memory_context: PgMemoryContexts, datum: Datum, is_null: bool, typoid: Oid, ) -> Option<Self>

Default implementation switched to the specified memory context and then simply calls FromDatum::from_datum(...) from within that context.

impl<'mcx, T> IntoIterator for VariadicArray<'mcx, T>

where for<'arr> T: UnboxDatum<As<'arr> = T> + 'static,

type Item = Option<<T as UnboxDatum>::As<'mcx>>

The type of the elements being iterated over.

type IntoIter = ArrayIntoIterator<'mcx, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'mcx, T: UnboxDatum> Serialize for VariadicArray<'mcx, T>

where for<'arr> <T as UnboxDatum>::As<'arr>: Serialize,

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.

where T: SqlTranslatable,

fn argument_sql() -> Result<SqlMapping, ArgumentError>

fn return_sql() -> Result<Returns, ReturnsError>

fn optional() -> bool

fn entity() -> FunctionMetadataTypeEntity

impl<T: FromDatum + UnboxDatum> UnboxDatum for VariadicArray<'_, T>

type As<'src> = VariadicArray<'src, T> where Self: 'src

Self with the lifetime 'src

unsafe fn unbox<'src>(d: Datum<'src>) -> VariadicArray<'src, T>

where Self: 'src,

Convert from Datum<'src> to T::As<'src>
