Implementations

impl FieldDefinition

pub fn new(name: impl Into<String>, field_type: FieldType) -> Self

Create a new field definition

pub fn with_description(self, description: impl Into<String>) -> Self

Add a description

pub fn with_default(self, default: Value) -> Self

Set default value

pub fn with_constraint(self, constraint: Constraint) -> Self

Trait Implementations

impl Clone for FieldDefinition

fn clone(&self) -> FieldDefinition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldDefinition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FieldDefinition

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FieldDefinition

fn eq(&self, other: &FieldDefinition) -> 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 Serialize for FieldDefinition

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
