pub struct PgTypeInfo(_);
Expand description

Type information for a PostgreSQL type.

Implementations§

source§

impl PgTypeInfo

source

pub fn kind(&self) -> &PgTypeKind

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

source

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.

source

pub const fn with_oid(oid: Oid) -> 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 built-in type, you should be fine. Otherwise, you will be better served using with_name.

impl From<PgTypeInfo> for AnyTypeInfo

source§

fn from(ty: PgTypeInfo) -> Self

Converts to this type from the input type.
source§

impl PartialEq<PgTypeInfo> for PgTypeInfo

source§

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
source§

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. Read more
source§

impl TypeInfo for PgTypeInfo

source§

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.
