Struct ColumnIdentityKey 

pub struct ColumnIdentityKey { /* private fields */ }

An opaque, dialect-aware identity key for a ColumnReference — the TableIdentityKey of its owning table (if any, folded by the table rule) plus the column name folded by the column rule. See TableIdentityKey for the identity-vs-matching and opacity notes.

Trait Implementations

impl Clone for ColumnIdentityKey

fn clone(&self) -> ColumnIdentityKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnIdentityKey

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

Formats the value using the given formatter.

impl Eq for ColumnIdentityKey

impl Hash for ColumnIdentityKey

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 ColumnIdentityKey

fn eq(&self, other: &ColumnIdentityKey) -> 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.
