Enum DataType 

#[non_exhaustive]
pub enum DataType {
    Boolean = 1,
    Integer8 = 2,
    Integer16 = 3,
    Integer32 = 4,
    Unsigned8 = 5,
    Unsigned16 = 6,
    Unsigned32 = 7,
    Real32 = 8,
    Real64 = 17,
    Integer64 = 21,
    Unsigned64 = 27,
    VisibleString = 9,
    OctetString = 10,
    Domain = 15,
}

A CANopen basic data type.

The discriminant is the CiA 301 data type index (the object index under which the type is described, e.g. UNSIGNED32 is 0x0007).

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.

Boolean = 1

BOOLEAN (0x0001), 1 byte.

Integer8 = 2

INTEGER8 (0x0002), 1 byte.

Integer16 = 3

INTEGER16 (0x0003), 2 bytes.

Integer32 = 4

INTEGER32 (0x0004), 4 bytes.

Unsigned8 = 5

UNSIGNED8 (0x0005), 1 byte.

Unsigned16 = 6

UNSIGNED16 (0x0006), 2 bytes.

Unsigned32 = 7

UNSIGNED32 (0x0007), 4 bytes.

Real32 = 8

REAL32 (0x0008), 4 bytes.

Real64 = 17

REAL64 (0x0011), 8 bytes.

Integer64 = 21

INTEGER64 (0x0015), 8 bytes.

Unsigned64 = 27

UNSIGNED64 (0x001B), 8 bytes.

VisibleString = 9

VISIBLE_STRING (0x0009), variable length (ASCII/UTF-8 text).

OctetString = 10

OCTET_STRING (0x000A), variable length (arbitrary bytes).

Domain = 15

DOMAIN (0x000F), variable length (arbitrary bytes).

Implementations

impl DataType

pub const fn index(self) -> u16

The CiA 301 data type index (e.g. 0x0007 for UNSIGNED32).

pub const fn from_index(index: u16) -> Option<Self>

The basic data type for a CiA 301 data type index, or None for an index this crate does not model.

pub const fn fixed_size(self) -> Option<usize>

The fixed encoded size of a value of this type in bytes, or None for a variable-length type (VISIBLE_STRING, OCTET_STRING, DOMAIN).

pub const fn is_variable(self) -> bool

Whether this is a variable-length type.

pub const fn size(self) -> usize

The fixed encoded size of a value of this type in bytes, or 0 for a variable-length type (whose size depends on the value — see fixed_size).

Trait Implementations
