Struct TypeInfo 

pub struct TypeInfo {
    pub oid: Oid,
    pub name: &'static str,
    pub kind: u8,
    pub category: u8,
    pub len: i16,
    pub elem: Oid,
    pub array: Oid,
    pub delim: u8,
}

The columns of pg_type that the wire format and the type rules read.

Fields

oid: Oid

name: &'static str

kind: u8

typtype: b for a base type, p for a pseudo-type, r for a range, m for a multirange.

category: u8

typcategory, the letter that the rules for implicit casts use.

len: i16

typlen: the size in bytes, -1 for a value of variable length and -2 for a C string.

elem: Oid

typelem: the element type of an array, or 0.

array: Oid

typarray: the array type of this type, or 0.

delim: u8

typdelim: the character between the elements of an array in the text format.

Implementations

impl TypeInfo

pub fn get(oid: Oid) -> Option<&'static TypeInfo>

The built-in type with this OID.

pub fn by_name(name: &str) -> Option<&'static TypeInfo>

The built-in type with this typname, such as int4 or _int4.

pub fn all() -> &'static [TypeInfo]

Every built-in type, in the order of the OIDs.

pub fn is_array(&self) -> bool

Whether the type is an array in the sense of SQL, which format_type writes as the element type and []. This is IsTrueArrayType with a storage that is not plain. So int2vector and oidvector are not arrays, but _record, which is a pseudo-type, is.

Trait Implementations

impl Clone for TypeInfo

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TypeInfo

impl Debug for TypeInfo

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

impl Eq for TypeInfo

impl PartialEq for TypeInfo

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