pub enum TyTupleField {
    Single(Option<String>, Option<Ty>),
    Wildcard(Option<Ty>),
}

Variants

Named tuple element.

Wildcard(Option<Ty>)

Placeholder for possibly many elements. Means “and other unmentioned columns”. Does not mean “all columns”.

Implementations

impl TyTupleField

pub fn is_single(&self) -> bool

Returns true if this is a TyTupleField::Single, otherwise false

pub fn as_single_mut( &mut self, ) -> Option<(&mut Option<String>, &mut Option<Ty>)>

Optionally returns mutable references to the inner fields if this is a TyTupleField::Single, otherwise None

pub fn as_single(&self) -> Option<(&Option<String>, &Option<Ty>)>

Optionally returns references to the inner fields if this is a TyTupleField::Single, otherwise None

pub fn into_single(self) -> Result<(Option<String>, Option<Ty>), Self>

Returns the inner fields if this is a TyTupleField::Single, otherwise returns back the enum in the Err case of the result

pub fn is_wildcard(&self) -> bool

Returns true if this is a TyTupleField::Wildcard, otherwise false

pub fn as_wildcard_mut(&mut self) -> Option<&mut Option<Ty>>

Optionally returns mutable references to the inner fields if this is a TyTupleField::Wildcard, otherwise None

pub fn as_wildcard(&self) -> Option<&Option<Ty>>

Optionally returns references to the inner fields if this is a TyTupleField::Wildcard, otherwise None

pub fn into_wildcard(self) -> Result<Option<Ty>, Self>

Returns the inner fields if this is a TyTupleField::Wildcard, otherwise returns back the enum in the Err case of the result

impl TyTupleField

pub fn ty(&self) -> Option<&Ty>

Trait Implementations

impl Clone for TyTupleField

fn clone(&self) -> TyTupleField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TyTupleField

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TyTupleField

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for TyTupleField

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for TyTupleField

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
