Struct ChangeUserOpts

Source 
pub struct ChangeUserOpts { /* private fields */ }
Expand description

COM_CHANGE_USER options.

Connection Opts are going to be updated accordingly upon COM_CHANGE_USER.

Opts won’t be updated by default, because default ChangeUserOpts will reuse connection’s user, pass and db_name.

Implementations§

Source§

impl ChangeUserOpts

Source

pub fn new() -> Self

Creates change user options that’ll reuse connection options.

Source

pub fn with_user(self, user: Option<String>) -> Self

Set Opts::user to the given value.

Source

pub fn with_pass(self, pass: Option<String>) -> Self

Set Opts::pass to the given value.

Source

pub fn with_db_name(self, db_name: Option<String>) -> Self

Set Opts::db_name to the given value.

Source

pub fn user(&self) -> Option<Option<&str>>

Returns user.

  • if None then self does not meant to change user
  • if Some(None) then self will clear user
  • if Some(Some(_)) then self will change user
Source

pub fn pass(&self) -> Option<Option<&str>>

Returns password.

  • if None then self does not meant to change password
  • if Some(None) then self will clear password
  • if Some(Some(_)) then self will change password
Source

pub fn db_name(&self) -> Option<Option<&str>>

Returns database name.

  • if None then self does not meant to change database name
  • if Some(None) then self will clear database name
  • if Some(Some(_)) then self will change database name
