Struct ColumnRef 

pub struct ColumnRef {
    pub name: Arc<str>,
}

Reference identifying a column used inside predicates.

This is a logical column reference using only the column name. Physical binding (resolving to schema indices) happens during query planning, not at predicate construction time.

Fields

name: Arc<str>

Canonical column name.

Implementations

impl ColumnRef

pub fn new<N>(name: N) -> Self

where N: Into<Arc<str>>,

Creates a new column reference from a name.

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 Eq for ColumnRef

impl From<ColumnRef> for Operand

fn from(value: ColumnRef) -> Self

Converts to this type from the input type.

impl Hash for ColumnRef

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
