Implementations

impl Type

pub fn promote(left: Type, right: Type) -> Type

Promote two Types to a common supertype, similar to Postgres expression evaluation.

impl Type

pub fn list_of(ty: Type) -> Type

pub fn is_number(&self) -> bool

pub fn is_bool(&self) -> bool

pub fn is_signed_integer(&self) -> bool

pub fn is_unsigned_integer(&self) -> bool

pub fn is_integer(&self) -> bool

pub fn is_floating_point(&self) -> bool

pub fn is_utf8(&self) -> bool

pub fn is_temporal(&self) -> bool

pub fn is_uuid(&self) -> bool

pub fn is_blob(&self) -> bool

pub fn is_option(&self) -> bool

pub fn inner_type(&self) -> &Type

Returns the inner type if this is an Option type, otherwise returns self

impl Type

pub fn to_u8(&self) -> u8

impl Type

pub fn from_u8(value: u8) -> Type

impl Type

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Type

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Type

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

Formats the value using the given formatter.

impl From<&Value> for Type

fn from(value: &Value) -> Type

Converts to this type from the input type.

impl FromStr for Type

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Type, <Type as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for Type

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

where __H: Hasher,

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 Type

fn cmp(&self, other: &Type) -> 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.

impl PartialEq for Type

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Type

fn partial_cmp(&self, other: &Type) -> 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.

impl Serialize for Type

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Type

impl StructuralPartialEq for Type
