Variants

Flags2

Contains Flags2 flags.

SqlMode

Contains SqlMode flags.

Catalog

Contains values in the following order:

• 1 byte length,
• length bytes catalog,
• NULL byte.

length + 2 bytes in total.

AutoIncrement

Contains values in the following order:

• 2 bytes unsigned little-endian auto_increment_increment,
• 2 bytes unsigned little-endian auto_increment_offset.

Four bytes in total.

Charset

Contains values in the following order:

• 2 bytes unsigned little-endian character_set_client,
• 2 bytes unsigned little-endian collation_connection,
• 2 bytes unsigned little-endian collation_server.

Six bytes in total.

TimeZone

Contains values in the following order:

• 1 byte length,
• length bytes timezone.

length + 1 bytes in total.

CatalogNz

Contains values in the following order:

• 1 byte length,
• length bytes catalog.

length + 1 bytes in total.

LcTimeNames

user_length + host_length + 2 bytes in total.

UpdatedDbNames

Contains values in the following order:

• 1 byte count,
• count times:
  • null-terminated db_name.

Trait Implementations

impl Clone for StatusVarKey

fn clone(&self) -> StatusVarKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StatusVarKey

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

Formats the value using the given formatter.

impl Hash for StatusVarKey

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 PartialEq<StatusVarKey> for StatusVarKey

fn eq(&self, other: &StatusVarKey) -> 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.

impl TryFrom<u8> for StatusVarKey

type Error = UnknownStatusVarKey

The type returned in the event of a conversion error.

fn try_from(
value: u8
) -> Result<StatusVarKey, <StatusVarKey as TryFrom<u8>>::Error>

Performs the conversion.
