Struct TypeId 

pub struct TypeId(pub Oid);

A type, by its OID in pg_type of the PostgreSQL pin.

Tuple Fields

0: Oid

Implementations

impl TypeId

pub const BOOL: TypeId

bool.

pub const BYTEA: TypeId

bytea.

pub const INT8: TypeId

int8.

pub const INT2: TypeId

int2.

pub const INT4: TypeId

int4.

pub const TEXT: TypeId

text.

pub const OID: TypeId

oid.

pub const FLOAT4: TypeId

float4.

pub const FLOAT8: TypeId

float8.

pub const DATE: TypeId

date.

pub const TIMESTAMP: TypeId

timestamp.

pub const TIMESTAMPTZ: TypeId

timestamptz.

pub const UUID: TypeId

uuid.

pub const M1: [TypeId; 13]

The types that M1 stores. Later milestones add the other types of the pin.

pub fn from_oid(oid: Oid) -> Option<TypeId>

The type with this OID, or None if M1 does not store it.

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

The name in pg_type.

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

The name that PostgreSQL gives in messages, from format_type_be.

pub fn width(self) -> Option<u8>

The bytes of a value in storage form, or None for a type whose values have their own length.

Trait Implementations

impl Clone for TypeId

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 TypeId

impl Debug for TypeId

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

Formats the value using the given formatter.

impl Display for TypeId

impl Eq for TypeId

impl Hash for TypeId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TypeId

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for TypeId

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for TypeId

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
