Struct MySQLDialect 

pub struct MySQLDialect;

Type-level marker for MySQL.

MySQL keeps signed and unsigned integer markers distinct, uses backtick identifiers, and has one native JSON type. It has no native UUID or time-zone-bearing datetime type: UUIDs use BINARY(16), while TimestampTz maps to session-time-zone-aware TIMESTAMP. Concrete wire-driver behavior remains outside this marker.
