Struct Buffer 

pub struct Buffer { /* private fields */ }

A frontend message under construction.

Implementations

impl Buffer

pub fn new() -> Self

pub fn into_bytes(self) -> Vec<u8>

pub fn startup(&mut self, parameters: &[(&str, &str)]) -> &mut Self

The startup packet, which has a length and a version but no type byte.

pub fn password(&mut self, password: &str) -> &mut Self

pub fn sasl_initial(&mut self, mechanism: &str, response: &str) -> &mut Self

pub fn sasl_response(&mut self, response: &str) -> &mut Self

pub fn query(&mut self, sql: &str) -> &mut Self

A simple query. Multiple statements are allowed but no parameters, so this is reserved for DDL and internal bookkeeping.

pub fn parse(&mut self, name: &str, sql: &str) -> &mut Self

Prepare an unnamed statement. Parameter types are left unspecified so the server infers them.

pub fn bind( &mut self, portal: &str, statement: &str, params: &[Option<String>], ) -> &mut Self

Bind parameters, sent in text format.

Text keeps the driver free of per-type binary encoders while remaining exact: the server parses each parameter with the type it inferred.

pub fn describe_portal(&mut self, portal: &str) -> &mut Self

pub fn execute(&mut self, portal: &str, max_rows: i32) -> &mut Self

pub fn sync(&mut self) -> &mut Self

pub fn terminate(&mut self) -> &mut Self
