Enum PropertyValue 

pub enum PropertyValue {
    Int8(i8),
    Uint8(u8),
    Int16(i16),
    Uint16(u16),
    Int32(i32),
    Uint32(u32),
    Int64(i64),
    Uint64(u64),
    String(String),
}

A property value with its associated type.

Used for device property values in DevicePropDesc, as well as for get/set device property operations.

Variants

Int8(i8)

Signed 8-bit integer.

Uint8(u8)

Unsigned 8-bit integer.

Int16(i16)

Signed 16-bit integer.

Uint16(u16)

Unsigned 16-bit integer.

Int32(i32)

Signed 32-bit integer.

Uint32(u32)

Unsigned 32-bit integer.

Int64(i64)

Signed 64-bit integer.

Uint64(u64)

Unsigned 64-bit integer.

String(String)

UTF-16LE encoded string.

Implementations

impl PropertyValue

pub fn to_bytes(&self) -> Vec<u8>

Serialize this property value to bytes.

pub fn from_bytes( buf: &[u8], data_type: PropertyDataType, ) -> Result<(Self, usize), Error>

Parse a property value from bytes given the expected data type.

Returns the parsed value and the number of bytes consumed.

pub fn data_type(&self) -> PropertyDataType

Get the data type of this property value.

Trait Implementations

impl Clone for PropertyValue

fn clone(&self) -> PropertyValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PropertyValue

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

Formats the value using the given formatter.

impl PartialEq for PropertyValue

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