Trait Implementations

impl Clone for StringNullableFieldUpdate

fn clone(&self) -> StringNullableFieldUpdate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringNullableFieldUpdate

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

Formats the value using the given formatter.

impl Default for StringNullableFieldUpdate

fn default() -> StringNullableFieldUpdate

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StringNullableFieldUpdate

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&str> for StringNullableFieldUpdate

fn from(v: &str) -> Self

Converts to this type from the input type.

impl From<String> for StringNullableFieldUpdate

fn from(v: String) -> Self

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

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

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