Trait Encode

pub trait Encode<'q, DB>
where
    DB: Database,
{
    // Required method
    fn encode_by_ref(
        &self,
        buf: &mut <DB as Database>::ArgumentBuffer<'q>,
    ) -> Result<IsNull, Box<dyn Error + Send + Sync>>;

    // Provided methods
    fn encode(
        self,
        buf: &mut <DB as Database>::ArgumentBuffer<'q>,

       where Self: Sized { ... }
    fn produces(&self) -> Option<<DB as Database>::TypeInfo> { ... }
    fn size_hint(&self) -> usize { ... }
}

Encode a single value to be sent to the database.

Required Methods

fn encode_by_ref( &self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

Writes the value of self into buf without moving self.

Where possible, make use of encode instead as it can take advantage of re-using memory.

Provided Methods

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

fn produces(&self) -> Option<<DB as Database>::TypeInfo>

fn size_hint(&self) -> usize

impl Encode<'_, Postgres> for BigDecimal

Note: BigDecimal Has a Larger Range than NUMERIC

BigDecimal can represent values with a far, far greater range than the NUMERIC type in Postgres can.

NUMERIC is limited 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.

Meanwhile, BigDecimal can theoretically represent a value with an arbitrary number of decimal digits, albeit with a maximum of 2⁶³ significant figures.

Because encoding in the current API design must be infallible, when attempting to encode a BigDecimal that cannot fit in the wire representation of NUMERIC, SQLx may instead encode a sentinel value that falls outside the allowed range but is still representable.

This will cause the query to return a DatabaseError with code 22P03 (invalid_binary_representation) and the error message invalid scale in external "numeric" value (though this may be subject to change).

However, BigDecimal should be able to decode any NUMERIC value except NaN, for which it has no representation.
