pub struct AsyncDieselConnectionManager<C> { /* private fields */ }

An connection manager for use with diesel-async.

See the concrete pool implementations for examples:

• deadpool
• bb8
• mobc

Implementations

impl<C> AsyncDieselConnectionManager<C>

pub fn new(connection_url: impl Into<String>) -> Self

where C: AsyncConnection + 'static,

Returns a new connection manager, which establishes connections to the given database URL.

pub fn new_with_setup( connection_url: impl Into<String>, setup: impl Fn(&str) -> BoxFuture<'_, ConnectionResult<C>> + Send + Sync + 'static, ) -> Self

Construct a new connection manger with a custom setup procedure

This can be used to for example establish a SSL secured postgres connection
