Enum Resolution 

#[non_exhaustive]
#[repr(i8)]
pub enum Resolution {
    Int8 = 0,
    Int16 = 1,
    Int32 = 2,
    Float = 3,
    Ignore = 4,
}

The resolution (data type) used when encoding or decoding a register value.

Each resolution type determines:

• The number of bytes used on the wire
• The scaling applied to convert between wire format and physical units
• The range of representable values

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Int8 = 0

8-bit signed integer (1 byte)

Int16 = 1

16-bit signed integer (2 bytes)

Int32 = 2

32-bit signed integer (4 bytes)

Float = 3

32-bit IEEE 754 float (4 bytes)

Ignore = 4

This register should be ignored/not transmitted

Implementations

impl Resolution

pub const fn size(self) -> usize

Returns the size in bytes for this resolution type.

Returns 0 for Ignore.

pub const fn type_code(self) -> u8

Returns the multiplex protocol type code for this resolution.

This is used in the wire protocol to identify the data type.

pub const fn from_type_code(code: u8) -> Option<Resolution>

Creates a Resolution from a type code.

Returns None if the type code is invalid.

pub const fn nan_value(self) -> i32

Returns the minimum representable value for integer types.

This value is used to represent NaN in the protocol.

pub const fn max_value(self) -> i32

Returns the maximum representable value for integer types.

Trait Implementations

impl Clone for Resolution

fn clone(&self) -> Resolution

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Resolution

impl Debug for Resolution

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

Formats the value using the given formatter.

impl Default for Resolution

fn default() -> Resolution

Returns the “default value” for a type.

impl Display for Resolution

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

Formats the value using the given formatter.

impl Eq for Resolution

impl PartialEq for Resolution

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