Display Definition Segment (DDS).

Fields

page_id: u16

The page_id (from generic segment header).

dds_version_number: u8

Version of this DDS (modulo 16).

display_window_flag: bool

Whether a window is defined (true) or the display set fills the full resolution (false).

reserved: u8

Reserved bits in body byte 0 (bits [2:0]).

display_width: u16

Maximum horizontal width in pixels minus 1 (0..4095).

display_height: u16

Maximum vertical height in lines minus 1 (0..4095).

display_window_horizontal_position_minimum: Option<u16>

Left-most pixel of the display window (present iff display_window_flag).

display_window_horizontal_position_maximum: Option<u16>

Right-most pixel of the display window (present iff display_window_flag).

display_window_vertical_position_minimum: Option<u16>

Upper-most line of the display window (present iff display_window_flag).

display_window_vertical_position_maximum: Option<u16>

Bottom line of the display window (present iff display_window_flag).

Trait Implementations

impl Clone for DisplayDefinitionSegment

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DisplayDefinitionSegment

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

Formats the value using the given formatter.

impl Eq for DisplayDefinitionSegment

impl<'a> From<DisplayDefinitionSegment> for AnySegment<'a>

fn from(s: DisplayDefinitionSegment) -> Self

Converts to this type from the input type.

impl<'a> Parse<'a> for DisplayDefinitionSegment

type Error = Error

The error type this implementer returns. Typically the enclosing crate’s Error enum.

fn parse(bytes: &'a [u8]) -> Result<Self>

Parse bytes as Self. Returns Err(Self::Error) on any protocol violation or buffer underrun.

impl PartialEq for DisplayDefinitionSegment

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl SegmentDef<'_> for DisplayDefinitionSegment

const SEGMENT_TYPE: u8 = segments::display_definition::SEGMENT_TYPE

Wire segment_type.

const NAME: &'static str = "DISPLAY_DEFINITION"

Diagnostic name. Convention: SCREAMING_SNAKE, suffix-free — PAGE_COMPOSITION, REGION_COMPOSITION, OBJECT_DATA.

impl Serialize for DisplayDefinitionSegment

Available on crate feature serde only.

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Serialize for DisplayDefinitionSegment

type Error = Error

The error type this implementer returns (usually the same as the corresponding Parse impl, but need not be).

fn serialized_len(&self) -> usize

Number of bytes serialize_into will write.

fn serialize_into(&self, buf: &mut [u8]) -> Result<usize, Self::Error>

Write the serialised form into buf. Returns the number of bytes written (always equal to serialized_len()).

fn try_to_bytes(&self) -> Result<Vec<u8>, Self::Error>

Allocate a Vec and serialize into it, returning the serializer’s error instead of panicking. This is the only allocate-and-serialize entry point: there is deliberately no panicking to_bytes (hand-built values, or values assembled from damaged wire data, can violate a wire constraint, so the error must reach the caller).
