Struct mysql_async::SystemVariable

pub struct SystemVariable<'a> { /* private fields */ }

This tracker type indicates that one or more tracked session system variables have been assigned a value.

Implementations

impl<'a> SystemVariable<'a>

pub fn new( name: impl Into<Cow<'a, [u8]>>, value: impl Into<Cow<'a, [u8]>>, ) -> SystemVariable<'a>

pub fn name_bytes(&self) -> &[u8]

Returns a raw name.

pub fn name_str(&self) -> Cow<'_, str>

Returns a name (lossy converted).

pub fn value_bytes(&self) -> &[u8]

Returns a raw value.

pub fn value_str(&self) -> Cow<'_, str>

Returns a value (lossy converted).

pub fn into_owned(self) -> SystemVariable<'static>

Returns a 'static version of self.

Trait Implementations

impl<'a> Clone for SystemVariable<'a>

fn clone(&self) -> SystemVariable<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SystemVariable<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for SystemVariable<'a>

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'de> MyDeserialize<'de> for SystemVariable<'de>

const SIZE: Option<usize> = None

Size hint of a serialized value (in bytes), if it’s constant.

type Ctx = ()

Some structs defines deserialization in the context of another value.

fn deserialize( _: <SystemVariable<'de> as MyDeserialize<'de>>::Ctx, buf: &mut ParseBuf<'de>, ) -> Result<SystemVariable<'de>, Error>

Deserializes self from the given buf.

impl MySerialize for SystemVariable<'_>

fn serialize(&self, buf: &mut Vec<u8>)

Serializes self into the buf.

impl<'a> PartialEq for SystemVariable<'a>

fn eq(&self, other: &SystemVariable<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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