Enum Scalar 

#[non_exhaustive]
pub enum Scalar {
    Int(i64),
    UInt(u64),
    Float(f64),
    Bool(bool),
    Str(String),
}

A literal value a column is compared with.

Variants (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.

Int(i64)

A signed integer; compares with any numeric column (decimals at their scale).

UInt(u64)

An unsigned integer; compares with any numeric column.

Float(f64)

A float; compares with any numeric column.

Bool(bool)

A boolean.

Str(String)

Text; compares with string and dictionary-of-string columns.
