Struct CacheIndexKeyList 

pub struct CacheIndexKeyList {
    pub keyword: CacheIndexKeyword,
    pub keys: ThinVec<Ident>,
    pub meta: Meta,
}

The optional {INDEX | KEY} (<key>[, ...]) list shared by the key-cache statements (MySQL’s opt_cache_key_list in its non-empty form).

INDEX and KEY are exact synonyms — the written spelling rides keyword for round-trip. The parenthesized list may be empty (INDEX ()); the parentheses are always written, so an empty keys is distinct from the clause’s absence (the enclosing Option<CacheIndexKeyList> being None). Each key is an index name, or the PRIMARY keyword naming the primary key — admitted here unquoted (key_usage_element: ident | PRIMARY_SYM) and preserved as an unquoted Ident (a backtick-quoted `PRIMARY` round-trips as a quoted name).

Fields

keyword: CacheIndexKeyword

Whether the list was introduced with INDEX or its KEY synonym.

keys: ThinVec<Ident>

The index names in source order; possibly empty (the INDEX () form).

meta: Meta

Source location and node identity.

Trait Implementations

impl Clone for CacheIndexKeyList

fn clone(&self) -> CacheIndexKeyList

Returns a duplicate of the value.

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

impl Eq for CacheIndexKeyList

impl Hash for CacheIndexKeyList

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

Feeds this value into the given Hasher.

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