Enum Nullable 

pub enum Nullable<T> {
    Unchanged,
    Null,
    Value(T),
}

Three-state type for PATCH request fields.

The Paddle API uses PATCH semantics where omitting a field means “don’t change”, sending null means “clear the value”, and sending a value means “set to this value”.

• Unchanged - Field will be omitted from serialization (no change)
• Null - Field will be serialized as null (clear the value)
• Value(T) - Field will be serialized as the contained value

Variants

Unchanged

Null

Value(T)

Implementations

pub fn is_unchanged(&self) -> bool

Trait Implementations

impl<T: Clone> Clone for Nullable<T>

fn clone(&self) -> Nullable<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Nullable<T>

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

Formats the value using the given formatter.

impl<T> Default for Nullable<T>

fn default() -> Self

Returns the “default value” for a type.

impl From<&str> for Nullable<String>

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<&str> for Nullable<CustomerID>

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<&str> for Nullable<AddressID>

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<&str> for Nullable<BusinessID>

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<&str> for Nullable<DiscountID>

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for Nullable<CustomerID>

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<String> for Nullable<AddressID>

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<String> for Nullable<BusinessID>

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<String> for Nullable<DiscountID>

fn from(s: String) -> Self

Converts to this type from the input type.

impl<T> From<T> for Nullable<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for Nullable<T>

fn eq(&self, other: &Nullable<T>) -> 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<T: Serialize> Serialize for Nullable<T>

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
