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 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.
§

type Value = PgValue

The concrete type used to hold an owned copy of the not-yet-decoded value that was received from the database.
§

type ValueRef<'r> = PgValueRef<'r>

The concrete type used to hold a reference to the not-yet-decoded value that has just been received from the database.
§

type Arguments<'q> = PgArguments

The concrete Arguments implementation for this database.
§

type ArgumentBuffer<'q> = PgArgumentBuffer

The concrete type used as a buffer for arguments while encoding.

§

impl Debug for Postgres

§

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

§

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.

fn fg(&self, value: Color) -> Painted<&T>

Returns a styled value derived from self with the foreground set to value.

This method should be used rarely. Instead, prefer to use color-specific builder methods like red() and green(), which have the same functionality but are pithier.

§Example

use yansi::{Paint, Color};

painted.fg(Color::White);

Set foreground color to white using white().

use yansi::Paint;

painted.white();

§

fn attr(&self, value: Attribute) -> Painted<&T>

Enables the styling [Attribute] value.

This method should be used rarely. Instead, prefer to use attribute-specific builder methods like bold() and underline(), which have the same functionality but are pithier.

§Example

Make text bold using attr():

use yansi::{Paint, Attribute};

painted.attr(Attribute::Bold);

Make text bold using using bold().

use yansi::Paint;

painted.bold();
§

Returns self with the attr() set to [Attribute :: Strike].

§Example
println!("{}", value.strike());
§

fn quirk(&self, value: Quirk) -> Painted<&T>

Enables the yansi [Quirk] value.

This method should be used rarely. Instead, prefer to use quirk-specific builder methods like mask() and wrap(), which have the same functionality but are pithier.
