Expand description

A tuple of arguments to be sent to the database.

Required Associated Types§

Source

type Database: Database

Required Methods§

Source

fn reserve(&mut self, additional: usize, size: usize)

Reserves the capacity for at least additional more values (of size total bytes) to be added to the arguments without a reallocation.

Source

fn add<T>(&mut self, value: T)
where T: 'q + Send + Encode<'q, Self::Database> + Type<Self::Database>,

Add the value to the end of the arguments.

Provided Methods§

Source

fn format_placeholder<W>(&self, writer: &mut W) -> Result<(), Error>
where W: Write,

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
