Struct TableIdentityKey 

pub struct TableIdentityKey { /* private fields */ }

An opaque, dialect-aware identity key for a TableReference.

Two references whose keys are equal denote the same table under the given dialect’s case-folding — e.g. users and USERS share a key in PostgreSQL, but not in a case-sensitive dialect. Use it to deduplicate references catalog-free, where the structural Eq / Hash on TableReference (case-sensitive, quote-sensitive) would over-count fold-equivalent spellings. (With a catalog, matched references are already canonicalized, so structural dedup suffices.)

The key is identity, not wildcard matching: every present segment is significant, so a bare users and a qualified public.users have different keys (they are different identities). The folded text is not observable — only equality / hashing.

Trait Implementations

impl Clone for TableIdentityKey

fn clone(&self) -> TableIdentityKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableIdentityKey

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

Formats the value using the given formatter.

impl Eq for TableIdentityKey

impl Hash for TableIdentityKey

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 TableIdentityKey

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