Struct rocket_db_pools::Initializer
source · [−]pub struct Initializer<D: Database>(_, _);
Expand description
A Fairing
which initializes a Database
and its connection pool.
A value of this type can be created for any type D
that implements
Database
via the Database::init()
method on the type. Normally, a
value of this type never needs to be constructed directly. This
documentation exists purely as a reference.
This fairing initializes a database pool. Specifically, it:
-
Reads the configuration at
database.db_name
, wheredb_name
isDatabase::NAME
. -
Sets
Config
defaults on the configuration figment. -
Calls
Pool::init()
. -
Stores the database instance in managed storage, retrievable via
Database::fetch()
.
The name of the fairing itself is Initializer<D>
, with D
replaced with
the type name D
unless a name is explicitly provided via
Self::with_name()
.
Implementations
