Trait sqlx::Decode

pub trait Decode<'r, DB>: Sized
where
    DB: Database,
{
    // Required method
    fn decode(
        value: <DB as HasValueRef<'r>>::ValueRef
    ) -> Result<Self, Box<dyn Error + Send + Sync>>;
}

A type that can be decoded from the database.

How can I implement Decode?

A manual implementation of Decode can be useful when adding support for types externally to SQLx.

The following showcases how to implement Decode to be generic over Database. The implementation can be marginally simpler if you remove the DB type parameter and explicitly use the concrete ValueRef and TypeInfo types.

struct MyType;

// DB is the database driver
// `'r` is the lifetime of the `Row` being decoded
impl<'r, DB: Database> Decode<'r, DB> for MyType
where
    // we want to delegate some of the work to string decoding so let's make sure strings
    // are supported by the database
    &'r str: Decode<'r, DB>
{
    fn decode(
        value: <DB as HasValueRef<'r>>::ValueRef,
    ) -> Result<MyType, Box<dyn Error + 'static + Send + Sync>> {
        // the interface of ValueRef is largely unstable at the moment
        // so this is not directly implementable

        // however, you can delegate to a type that matches the format of the type you want
        // to decode (such as a UTF-8 string)

        let value = <&str as Decode<DB>>::decode(value)?;

        // now you can parse this into your type (assuming there is a `FromStr`)

        Ok(value.parse()?)
    }
}

Required Methods

fn decode( value: <DB as HasValueRef<'r>>::ValueRef ) -> Result<Self, Box<dyn Error + Send + Sync>>

Decode a new value of this type using a raw value from the database.

Note: NaN

BigDecimal has a greater range than NUMERIC (see the corresponding Encode impl for details) but cannot represent NaN, so decoding may return an error.

impl Decode<'_, Postgres> for BitVec

impl Decode<'_, Postgres> for Decimal

Note: rust_decimal::Decimal Has a Smaller Range than NUMERIC

NUMERIC is can have up to 131,072 digits before the decimal point, and 16,384 digits after it. See [Section 8.1, Numeric Types] of the Postgres manual for details.

However, rust_decimal::Decimal is limited to a maximum absolute magnitude of 2⁹⁶ - 1, a number with 67 decimal digits, and a minimum absolute magnitude of 10^-28, a number with, unsurprisingly, 28 decimal digits.

Thus, in contrast with BigDecimal, NUMERIC can actually represent every possible value of rust_decimal::Decimal, but not the other way around. This means that encoding should never fail, but decoding can.
