Struct mysql::Opts [−][src]
pub struct Opts(_);
Expand description
Mysql connection options.
Build one with OptsBuilder
.
Implementations
Address of mysql server (defaults to 127.0.0.1
). Hostnames should also work.
TCP port of mysql server (defaults to 3306
).
Socket path on unix or pipe name on windows (defaults to None
).
Database name (defaults to None
).
The timeout for each attempt to write to the server.
The timeout for each attempt to write to the server.
Prefer socket connection (defaults to true
).
Will reconnect via socket (or named pipe on windows) after TCP connection
to 127.0.0.1
if true
.
Will fall back to TCP on error. Use socket
option to enforce socket connection.
Driver will require SSL connection if this option isn’t None
(default to None
).
Whether TCP_NODELAY
will be set for mysql connection.
TCP keep alive time for mysql connection.
Callback to handle requests for local files.
Tcp connect timeout (defaults to None
).
Bind address for a client (defaults to None
).
Use carefully. Will probably make pool unusable because of address already in use errors.
Number of prepared statements cached on the client side (per connection).
Defaults to DEFAULT_STMT_CACHE_SIZE
.
Can be defined using stmt_cache_size
connection url parameter.
If not None
, then client will ask for compression if server supports it
(defaults to None
).
Can be defined using compress
connection url parameter with values:
true
- library defined default compression level;fast
- library defined fast compression level;best
- library defined best compression level;0
,1
, …,9
- explicitly defined compression level where0
stands for “no compression”;
Note that compression level defined here will affect only outgoing packets.
Additional client capabilities to set (defaults to empty).
This value will be OR’ed with other client capabilities during connection initialisation.
Note
It is a good way to set something like CLIENT_FOUND_ROWS
but you should note that it
won’t let you to interfere with capabilities managed by other options (like
CLIENT_SSL
or CLIENT_COMPRESS
). Also note that some capabilities are reserved,
pointless or may broke the connection, so this option should be used with caution.
Connect attributes
This value is sent to the server as custom name-value attributes.
You can see them from performance_schema tables: session_account_connect_attrs
and session_connect_attrs
when all of the following conditions
are met.
- The server is MySQL 5.6 or later, or MariaDB 10.0 or later.
performance_schema
is on.performance_schema_session_connect_attrs_size
is -1 or big enough to store specified attributes.
Note
Attribute names that begin with an underscore (_
) are not set by
application programs because they are reserved for internal use.
The following attributes are sent in addition to ones set by programs.
name | value |
---|---|
_client_name | The client library name (rust-mysql-simple ) |
_client_version | The client library version |
_os | The operation system (target_os cfg feature) |
_pid | The client proces ID |
_platform | The machine platform (target_arch cfg feature) |
program_name | The first element of std::env::args if program_name isn’t set by programs. |
Disables mysql_old_password
plugin (defaults to true
).
Available via secure_auth
connection url parameter.
