Struct mysql::ChangeUserOpts

pub struct ChangeUserOpts { /* private fields */ }

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

impl ChangeUserOpts

pub const DEFAULT: Self = _

pub fn new() -> Self

Creates change user options that’ll reuse connection options.

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

Set Opts::get_user to the given value.

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

Set Opts::get_pass to the given value.

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

Set Opts::get_db_name to the given value.

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

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

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

Trait Implementations

impl Clone for ChangeUserOpts

fn clone(&self) -> ChangeUserOpts

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChangeUserOpts

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ChangeUserOpts

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<ChangeUserOpts> for ChangeUserOpts

fn eq(&self, other: &ChangeUserOpts) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
