#[non_exhaustive]
pub enum NumericRepresentation<'a> { Tiny(i8), Small(i16), Medium(i32), Big(i64), Float(f32), Double(f64), Decimal(&'a [u8]), }
Available on crate feature mysql_backend only.
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.
