Enum TableLockKind 

pub enum TableLockKind {
    Read,
    ReadLocal,
    Write,
}

The lock kind a MySQL TableLock acquires (lock_option in mysql sql_yacc.yy). Only these three spellings are grammar-valid on mysql:8.4.10 — the historical (pre-8.0) LOW_PRIORITY WRITE modifier is ER_PARSE_ERROR there (engine-measured), so it is deliberately not a variant.

Variants

Read

READ — a shared read lock.

ReadLocal

READ LOCAL — a shared read lock permitting concurrent non-conflicting inserts.

Write

WRITE — an exclusive write lock.

Trait Implementations
