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

length + 2 bytes in total.

AutoIncrement = 3

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.

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 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.
