pub struct ColumnRef {
    pub name: &'static str,
    pub table: &'static str,
    pub schema: &'static str,
}

Reference to a table column.

Fields

name: &'static str

Column name.

table: &'static str

Table name.

schema: &'static str

Schema name (may be empty).

Implementations

impl ColumnRef

pub fn table(&self) -> TableRef

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<(), Error>

Formats the value using the given formatter.

impl Default for ColumnRef

fn default() -> ColumnRef

Returns the “default value” for a type.

impl Expression for ColumnRef

fn write_query( &self, writer: &dyn SqlWriter, context: &mut Context, out: &mut String, )

Serialize the expression into the output string using the sql writer.

fn is_ordered(&self) -> bool

Whether this expression carries ordering information.

impl<'a> From<&'a ColumnDef> for &'a ColumnRef

fn from(value: &'a ColumnDef) -> &'a ColumnRef

Converts to this type from the input type.

impl OpPrecedence for ColumnRef

fn precedence(&self, _writer: &dyn SqlWriter) -> i32

Lower numbers bind weaker, writers parenthesize when child precedence <= operator precedence.

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 Copy for ColumnRef

impl Eq for ColumnRef

impl StructuralPartialEq for ColumnRef
