Implementations

impl Type

pub fn from_oid(oid: u32) -> Option<Type>

Returns the type corresponding to the provided OID, if the OID is known.

pub(crate) fn inner(&self) -> &'static Type

pub fn name(&self) -> &'static str

Returns the name that PostgreSQL uses for this type.

pub fn oid(&self) -> u32

Returns the OID of this type.

pub fn typlen(&self) -> i16

Returns the number of bytes in the binary representation of this type, or -1 if the type has a variable-length representation.

pub fn to_scalar_type_lossy(&self) -> ScalarType

Provides a ScalarType from self, but without necessarily associating any meaningful values within the returned type.

For example Type::Numeric returns SScalarType::Numeric { scale: None }, meaning that its scale might need values from elsewhere.
