Enum ColumnSource 

pub enum ColumnSource {
    Source {
        namespace: Fragment,
        source: Fragment,
    },
    Alias(Fragment),
}

How a column is qualified in plans (always fully qualified)

Variants

Source

Fully qualified by namespace.source

Fields

namespace: Fragment

source: Fragment

Alias(Fragment)

Qualified by alias (which maps to a fully qualified source)

Implementations

impl ColumnSource

pub fn into_owned(self) -> ColumnSource

pub fn to_static(&self) -> ColumnSource

pub fn as_fragment(&self) -> &Fragment

Trait Implementations

impl Clone for ColumnSource

fn clone(&self) -> ColumnSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnSource

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ColumnSource

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ColumnSource

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
