Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Tiny(i8)
Corresponds to MYSQL_TYPE_TINY
Small(i16)
Corresponds to MYSQL_TYPE_SHORT
Medium(i32)
Corresponds to MYSQL_TYPE_INT24
and MYSQL_TYPE_LONG
Big(i64)
Corresponds to MYSQL_TYPE_LONGLONG
Float(f32)
Corresponds to MYSQL_TYPE_FLOAT
Double(f64)
Corresponds to MYSQL_TYPE_DOUBLE
Decimal(&'a [u8])
Corresponds to MYSQL_TYPE_DECIMAL
and MYSQL_TYPE_NEWDECIMAL
