Enum Value 

#[non_exhaustive]
pub enum Value {
    Null,
    Bool(bool),
    Int(i64),
    Float(f64),
    Text(String),
    Bytes(Vec<u8>),
}

A portable parameter or column value. Deliberately narrow: what a key-value or migration statement needs. A program with richer types uses the driver’s own handle.

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.

Null

SQL NULL.

Bool(bool)

Boolean.

Int(i64)

64-bit integer (also read from narrower integer columns).

Float(f64)

64-bit float (also read from single-precision columns).

Text(String)

Text.

Bytes(Vec<u8>)

Bytes (BYTEA, BLOB).
