pub const CLIENT_RESERVED: CapabilityFlags

pub const CLIENT_SECURE_CONNECTION: CapabilityFlags

pub const CLIENT_MULTI_STATEMENTS: CapabilityFlags

Enable/disable multi-stmt support. Also sets CLIENT_MULTI_RESULTS. Currently not checked anywhere.

Requires

CLIENT_PROTOCOL_41

pub const CLIENT_PS_MULTI_RESULTS: CapabilityFlags

Server

pub const CLIENT_PLUGIN_AUTH: CapabilityFlags

Client supports plugin authentication.

Server

Sends extra data in Initial Handshake Packet and supports the pluggable authentication protocol.

Client

Supports authentication plugins.

Requires

CLIENT_PROTOCOL_41

pub const CLIENT_CONNECT_ATTRS: CapabilityFlags

Client supports connection attributes.

Server

Permits connection attributes in Protocol::HandshakeResponse41.

Client

Sends connection attributes in Protocol::HandshakeResponse41.

pub const CLIENT_PLUGIN_AUTH_LENENC_CLIENT_DATA: CapabilityFlags

Enable authentication response packet to be larger than 255 bytes. When the ability to change default plugin require that the initial password field in the Protocol::HandshakeResponse41 paclet can be of arbitrary size. However, the 4.1 client-server protocol limits the length of the auth-data-field sent from client to server to 255 bytes. The solution is to change the type of the field to a true length encoded string and indicate the protocol change with this client capability flag.

Server

Understands length-encoded integer for auth response data in Protocol::HandshakeResponse41.

Client

Length of auth response data in Protocol::HandshakeResponse41 is a length-encoded integer.

Note

The flag was introduced in 5.6.6, but had the wrong value.

pub const CLIENT_CAN_HANDLE_EXPIRED_PASSWORDS: CapabilityFlags

Don't close the connection for a user account with expired password.

pub const CLIENT_SESSION_TRACK: CapabilityFlags

Capable of handling server state change information. Its a hint to the server to include the state change information in OK_Packet.

Server

Can set SERVER_SESSION_STATE_CHANGED in the SERVER_STATUS_flags_enum and send Session State Information in a OK_Packet.

Client

Expects the server to send Session State Information in a OK_Packet.

pub const CLIENT_DEPRECATE_EOF: CapabilityFlags

Client no longer needs EOF_Packet and will use OK_Packet instead.

Server

Can send OK after a Text Resultset.

Client

Expects an OK_Packet (instead of EOF_Packet) after the resultset rows of a Text Resultset.

Background

To support CLIENT_SESSION_TRACK, additional information must be sent after all successful commands. Although the OK_Packet is extensible, the EOF_Packet is not due to the overlap of its bytes with the content of the Text Resultset Row.

Therefore, the EOF_Packet in the Text Resultset is replaced with an OK_Packet. EOF_Packet is deprecated as of MySQL 5.7.5.

pub const CLIENT_PROGRESS_OBSOLETE: CapabilityFlags

Client or server supports progress reports within error packet.

pub const CLIENT_SSL_VERIFY_SERVER_CERT: CapabilityFlags

Verify server certificate. Client only flag.

Deprecated in favor of –ssl-mode.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<CapabilityFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> CapabilityFlags
