Implementations

impl TypeModifier

pub fn is_optional(&self) -> bool

Check if the field is optional.

pub fn is_list(&self) -> bool

Check if the field is a list.

Trait Implementations

impl Clone for TypeModifier

fn clone(&self) -> TypeModifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeModifier

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TypeModifier

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TypeModifier

fn eq(&self, other: &TypeModifier) -> 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 TypeModifier

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 Copy for TypeModifier
