Struct cdbc_pg::PgTypeInfo

pub struct PgTypeInfo(_);

Type information for a PostgreSQL type.

Implementations

impl PgTypeInfo

pub fn kind(&self) -> &PgTypeKind

Returns the kind (simple, array, enum, etc.) for this type.

pub const fn with_name(name: &'static str) -> Self

Create a PgTypeInfo from a type name.

The OID for the type will be fetched from Postgres on use of a value of this type. The fetched OID will be cached per-connection.

pub const fn with_oid(oid: u32) -> Self

Create a PgTypeInfo from an OID.

Note that the OID for a type is very dependent on the environment. If you only ever use one database or if this is an unhandled build-in type, you should be fine. Otherwise, you will be better served using with_name.

Trait Implementations

impl Clone for PgTypeInfo

fn clone(&self) -> PgTypeInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PgTypeInfo

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

Formats the value using the given formatter.

impl Deref for PgTypeInfo

type Target = PgType

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for PgTypeInfo

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

Deserialize this value from the given Serde deserializer.

impl Display for PgTypeInfo

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

Formats the value using the given formatter.

impl PartialEq<PgTypeInfo> for PgTypeInfo

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Serialize for PgTypeInfo

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

Serialize this value into the given Serde serializer.

impl TypeInfo for PgTypeInfo

fn name(&self) -> &str

Returns the database system name of the type. Length specifiers should not be included. Common type names are VARCHAR, TEXT, or INT. Type names should be uppercase. They should be a rough approximation of how they are written in SQL in the given database.

fn is_null(&self) -> bool
