Trait Implementations

impl Database for Postgres

type Connection = PgConnection

The concrete Connection implementation for this database.

type TransactionManager = PgTransactionManager

The concrete TransactionManager implementation for this database.

type Row = PgRow

The concrete Row implementation for this database.

type QueryResult = PgQueryResult

The concrete QueryResult implementation for this database.

type Column = PgColumn

The concrete Column implementation for this database.

type TypeInfo = PgTypeInfo

The concrete TypeInfo implementation for this database.

const NAME: &'static str = "PostgreSQL"

The display name for this database driver.

const URL_SCHEMES: &'static [&'static str] = _

The schemes for database URLs that should match this driver.

impl Debug for Postgres

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<const N: usize> Decode<'_, Postgres> for [u8; N]

fn decode( value: PgValueRef<'_> ) -> Result<[u8; N], Box<dyn Error + Send + Sync>>

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

impl Decode<'_, Postgres> for BigDecimal

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.

fn decode( value: PgValueRef<'_> ) -> Result<BigDecimal, Box<dyn Error + Send + Sync>>

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

impl Decode<'_, Postgres> for BitVec

fn decode(value: PgValueRef<'_>) -> Result<BitVec, Box<dyn Error + Send + Sync>>

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

impl Decode<'_, Postgres> for Box<[u8]>

fn decode( value: PgValueRef<'_> ) -> Result<Box<[u8]>, Box<dyn Error + Send + Sync>>

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

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.

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.
