The possible relative types that are supported.

The variants of this enum include primitive fixed size types as well as parametric or nested types. Currently the Rust implementation supports the following nested types:

• List<T>
• Struct<T, U, V, ...>

Nested types can themselves be nested within other arrays. For more information on these types please see here.

Methods

impl DataType

pub fn to_json(&self) -> Value

Generate a JSON representation of the data type

Trait Implementations

impl PartialOrd<DataType> for DataType

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl PartialEq<DataType> for DataType

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

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

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

This method tests for !=.

impl Clone for DataType

fn clone(&self) -> DataType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for DataType

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

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

Returns max if self is greater than max, and min if self is less than min. Otherwise this will return self. Panics if min > max.

impl Eq for DataType

impl Debug for DataType

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

Formats the value using the given formatter.

impl Hash for DataType

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, 

Feeds a slice of this type into the given [Hasher].

impl<'de> Deserialize<'de> for DataType

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

Deserialize this value from the given Serde deserializer.

impl Serialize for DataType

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

Serialize this value into the given Serde serializer.
