PTP property data type codes.

These codes identify the data type of property values in property descriptors.

Variants

Undefined = 0

Undefined type (0x0000).

Int8 = 1

Signed 8-bit integer (0x0001).

Uint8 = 2

Unsigned 8-bit integer (0x0002).

Int16 = 3

Signed 16-bit integer (0x0003).

Uint16 = 4

Unsigned 16-bit integer (0x0004).

Int32 = 5

Signed 32-bit integer (0x0005).

Uint32 = 6

Unsigned 32-bit integer (0x0006).

Int64 = 7

Signed 64-bit integer (0x0007).

Uint64 = 8

Unsigned 64-bit integer (0x0008).

Int128 = 9

Signed 128-bit integer (0x0009, rarely used).

Uint128 = 10

Unsigned 128-bit integer (0x000A, rarely used).

Unknown(u16)

Unknown type code.

String = 65_535

UTF-16LE string (0xFFFF).

Implementations

impl PropertyDataType

pub fn byte_size(&self) -> Option<usize>

Returns the byte size of this data type.

Returns None for variable-length types (String) and unsupported types (Undefined, Int128, Uint128, Unknown).

Trait Implementations

impl Clone for PropertyDataType

fn clone(&self) -> PropertyDataType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PropertyDataType

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

Formats the value using the given formatter.

impl From<PropertyDataType> for u16

fn from(enum_value: PropertyDataType) -> Self

Converts to this type from the input type.

impl From<u16> for PropertyDataType

fn from(number: u16) -> Self

Converts to this type from the input type.

impl FromPrimitive for PropertyDataType

type Primitive = u16

fn from_primitive(number: Self::Primitive) -> Self

impl Hash for PropertyDataType

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 PartialEq for PropertyDataType

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

impl Copy for PropertyDataType
