Expand description

Represents all possible forms MySQL transmits integers

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)`

Correponds to MYSQL_TYPE_TINY

`Small(i16)`

Correponds to MYSQL_TYPE_SHORT

`Medium(i32)`

Correponds to MYSQL_TYPE_INT24 and MYSQL_TYPE_LONG

`Big(i64)`

Correponds to MYSQL_TYPE_LONGLONG

`Float(f32)`

Correponds to MYSQL_TYPE_FLOAT

`Double(f64)`

Correponds to MYSQL_TYPE_DOUBLE

`Decimal(&'a [u8])`

Correponds to MYSQL_TYPE_DECIMAL and MYSQL_TYPE_NEWDECIMAL
