Enum ColumnSource 

pub enum ColumnSource<'a> {
    Source {
        namespace: Fragment<'a>,
        source: Fragment<'a>,
    },
    Alias(Fragment<'a>),
}

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

Variants

Source

Fully qualified by namespace.source

Fields

namespace: Fragment<'a>

source: Fragment<'a>

Alias(Fragment<'a>)

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

Implementations

impl<'a> ColumnSource<'a>

pub fn into_owned(self) -> ColumnSource<'static>

pub fn to_static(&self) -> ColumnSource<'static>

pub fn as_fragment(&self) -> &Fragment<'a>

Trait Implementations

impl<'a> Clone for ColumnSource<'a>

fn clone(&self) -> ColumnSource<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ColumnSource<'a>

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

Formats the value using the given formatter.

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

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> PartialEq for ColumnSource<'a>

fn eq(&self, other: &ColumnSource<'a>) -> 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<'a> Serialize for ColumnSource<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
