Enum IndexAlgorithm 

pub enum IndexAlgorithm {
    Default,
    Inplace,
    Instant,
    Copy,
}

The online-DDL ALGORITHM value (alter_algorithm_option_value). DEFAULT is a keyword; the rest are matched case-insensitively as identifiers, and an unknown value is a binding reject (ER_UNKNOWN_ALTER_ALGORITHM 1800), not a syntax error — so only these four bind.

Variants

Default

DEFAULT — let the server choose.

Inplace

INPLACE — rebuild in place where supported.

Instant

INSTANT — metadata-only change where supported.

Copy

COPY — rebuild via a table copy.
