pub struct Buffer<'a> { /* private fields */ }

A single connection uses just two buffers, allocated at the beginning of the connection. This type is a view into one of these buffer, which can be used to send orders via the provided methods.

Implementations

impl<'a> Buffer<'a>

pub fn parse<Name: AsRef<[u8]>>(
    &mut self,
    statement_name: Name,
    statement: &str,
    parameter_types: &[SqlType]
)

Parse a statement.

pub fn named_bind<'b, 'c>(
    &'b mut self,
    portal_name: &'c str,
    statement: &'static str,
    parameters: &[&dyn ToSql]
) -> Portal<'b, 'a, 'c>

Bind a statement to parameters and a “portal”, which is a result identifier. If only one statement is executed at a time, the unnamed portal (i.e. "") works.

pub fn bind<'b>(
    &'b mut self,
    statement: &'static str,
    parameters: &[&dyn ToSql]
) -> Portal<'b, 'a, 'static>

Bind a statement to parameters and a “portal”, which is a result identifier. If only one statement is executed at a time, the unnamed portal (i.e. "") works.

pub fn bind_unnamed<'b>(
    &'b mut self,
    statement: &str,
    parameters: &[&dyn ToSql]
) -> Portal<'b, 'a, 'static>

Bind a statement to parameters and a “portal”, which is a result identifier. If only one statement is executed at a time, the unnamed portal (i.e. "") works.

pub fn flush(&mut self)

Ask the server to flush.
