Struct ColumnRef 

pub struct ColumnRef {
    pub table: Option<TableName>,
    pub column: ColumnName,
}

A column reference, optionally qualified with table/alias.

Examples:

• "id" (unqualified)
• "users"."id" (qualified with table name)
• "t0"."id" (qualified with table alias)

Fields

table: Option<TableName>

Table name or alias qualifier. Renders as "table". prefix.

Example: "users" in "users"."id", or "t0" in "t0"."id"

column: ColumnName

The column name. Renders as "column".

Example: "id" in "users"."id"

Implementations

impl ColumnRef

pub fn new(column: ColumnName) -> Self

pub fn qualified(table: TableName, column: ColumnName) -> Self

Trait Implementations

impl Clone for ColumnRef

fn clone(&self) -> ColumnRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnRef

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

Formats the value using the given formatter.

impl PartialEq for ColumnRef

fn eq(&self, other: &ColumnRef) -> 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 Render for ColumnRef

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

impl StructuralPartialEq for ColumnRef
