Implementations

impl Relation

pub fn as_extern_ref_mut(
    &mut self
) -> Option<(&mut TableExternRef, &mut Vec<ColumnDecl>)>

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

pub fn as_extern_ref(&self) -> Option<(&TableExternRef, &Vec<ColumnDecl>)>

Optionally returns references to the inner fields if this is a Relation::ExternRef, otherwise None

pub fn into_extern_ref(self) -> Result<(TableExternRef, Vec<ColumnDecl>), Self>

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

pub fn as_pipeline_mut(&mut self) -> Option<&mut Vec<Transform>>

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

pub fn as_pipeline(&self) -> Option<&Vec<Transform>>

Optionally returns references to the inner fields if this is a Relation::Pipeline, otherwise None

pub fn into_pipeline(self) -> Result<Vec<Transform>, Self>

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

pub fn as_literal_mut(
    &mut self
) -> Option<(&mut RelationLiteral, &mut Vec<ColumnDecl>)>

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

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

pub fn as_s_string_mut(
    &mut self
) -> Option<(&mut Vec<InterpolateItem<Expr>>, &mut Vec<ColumnDecl>)>

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

Trait Implementations

impl Clone for Relation

fn clone(&self) -> Relation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Relation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Relation

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

Deserialize this value from the given Serde deserializer.

impl PartialEq<Relation> for Relation

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Relation

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

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Relation
