Trait Implementations

impl Clone for DevEnum

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DevEnum

impl Debug for DevEnum

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

Formats the value using the given formatter.

impl Default for DevEnum

fn default() -> Self

Returns the “default value” for a type.

impl Element for DevEnum

const INLINE_FIXED: bool

Whether a scalar of this type is held in place of a storage, which only a packed type small enough can be.

type Ref<'a> = DevEnum

How one value is given out: by value for a packed type, borrowed for a string.

type Spans = PackedSpans<DevEnum>

Where the values are in the storage.

fn validate(bytes: &[u8]) -> bool

Whether these octets are one valid value.

unsafe fn read<'a>(ptr: *const u8, _len: usize) -> DevEnum

where DevEnum: 'a,

The value in these octets.

fn fmt_row<'a, I>(values: I, f: &mut Formatter<'_>) -> Result

where I: Iterator<Item = Self::Ref<'a>>, Self: 'a,

Format the values of one row of a buffer for Debug, along its first dimension, within the brackets of that row: separated by commas unless a type has a better way.

impl Eq for DevEnum

impl Hash for DevEnum

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

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 PackedElement for DevEnum

fn validate_all(_bytes: &[u8]) -> bool

Whether the octets of a whole number of consecutive values are all valid values, in a single pass: what octets are checked with when they are cast, and what Element::validate is for one value.

impl PartialEq for DevEnum

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for DevEnum

impl TangoElement for DevEnum

const ATTR_KIND: AttrDataKind = AttrDataKind::Enum

const CMD_SCALAR_KIND: Option<CommandDataKind> = None

The kind of a command argument of one such value, absent if none can be.

const CMD_ARRAY_KIND: Option<CommandDataKind> = None

The kind of a command argument of an array of such values, absent if none can be.

fn wrap(format: ValueFormat<Self>) -> Value

fn unwrap(data: Value) -> Result<ValueFormat<Self>, Value>

fn unwrap_ref(data: &Value) -> Option<&ValueFormat<Self>>

impl TryFrom<&Value> for DevEnum

type Error = Error

fn try_from(data: &Value) -> Result<Self, Error>

Performs the conversion.

impl TryFrom<Value> for DevEnum

type Error = Error

The type returned in the event of a conversion error.

fn try_from(data: Value) -> Result<Self, Error>

Performs the conversion.
