Fields

space: i32

offset: u32

length_words: u32

bit_index: u32

byte_order: i32

word_order: i32

sign_magnitude: bool

v0.4 — sign-magnitude instead of two’s complement

stride_words: u32

v0.4 — repeating-array element stride (§14.1)

model_relative_offset: u32

v0.4 — offset within a discovered model (§7.3)

composed: Option<Box<ComposedMapping>>

allowed_function_codes: Vec<u32>

§7.2

string_encoding: Option<StringEncoding>

§15

storage_type: i32

§14 (composed sub-mappings). Storage type of the sub-value; determines signedness (and width when no bit window is set). Spec’d since v0.4 §14; the field was missing from the schema.

bit_offset: u32

v0.5 §14 — bit window over the assembled sub-mapping window, for values whose mantissa and exponent share a register word (embedded decade exponent, e.g. Iskra T5/T6, Eaton PXM “GENERAL FORMAT”). LSB = 0, counted across the whole mapped window (as RegisterField §13.1). A sub-value with a bit window sign-extends from bit_length, not the storage width. bit_length = 0 means “no bit window”.

bit_length: u32

length_ref: Option<PointRef>

v0.5 §11.7 — dynamic element/word count for this mapping’s read, resolved from another point in the same device profile at read time (e.g. an “Output Message Length” register gating a variable-length signature-blob read). Effective word count = the decoded value of the referenced point, clamped to length_words as an upper bound if length_words is also set. Must resolve within the same device profile (MDE407); must reference an integer-valued point (MDE505); must not form a cycle (MDE506).

Implementations

impl Mapping

pub fn space(&self) -> AddressSpace

Returns the enum value of space, or the default if the field is set to an invalid enum value.

pub fn set_space(&mut self, value: AddressSpace)

Sets space to the provided enum value.

pub fn byte_order(&self) -> ByteOrder

Returns the enum value of byte_order, or the default if the field is set to an invalid enum value.

pub fn set_byte_order(&mut self, value: ByteOrder)

Sets byte_order to the provided enum value.

pub fn word_order(&self) -> WordOrder

Returns the enum value of word_order, or the default if the field is set to an invalid enum value.

pub fn set_word_order(&mut self, value: WordOrder)

Sets word_order to the provided enum value.

pub fn storage_type(&self) -> StorageType

Returns the enum value of storage_type, or the default if the field is set to an invalid enum value.

pub fn set_storage_type(&mut self, value: StorageType)

Sets storage_type to the provided enum value.

Trait Implementations

impl Clone for Mapping

fn clone(&self) -> Mapping

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mapping

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

Formats the value using the given formatter.

impl Default for Mapping

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Mapping

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for Mapping

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Mapping

fn eq(&self, other: &Mapping) -> 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 Serialize for Mapping

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
