Enum IndexLockAlgorithmOption 

pub enum IndexLockAlgorithmOption {
    Algorithm {
        equals: bool,
        value: IndexAlgorithm,
    },
    Lock {
        equals: bool,
        value: IndexLock,
    },
}

One entry of a DROP INDEX … ON … (or online ALTER TABLE) opt_index_lock_and_algorithm tail — an ALGORITHM or a LOCK execution hint. Each records whether the optional = (opt_equal) was written so the surface form round-trips verbatim.

Variants

Algorithm

ALGORITHM [=] {DEFAULT | INPLACE | INSTANT | COPY}.

Fields

equals: bool

Whether the optional = was written between the keyword and the value.

value: IndexAlgorithm

The chosen algorithm.

Lock

LOCK [=] {DEFAULT | NONE | SHARED | EXCLUSIVE}.

Fields

equals: bool

Whether the optional = was written between the keyword and the value.

value: IndexLock

The chosen lock level.
