Trait Implementations

impl Database for Postgres

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.

type Column = PgColumn

The concrete Column implementation for this database.

type TypeInfo = PgTypeInfo

The concrete TypeInfo implementation for this database.

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 + Sync + Send>>

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 + Sync + Send>>

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.
