Struct Mapping 

pub struct Mapping {
    pub reversed_groups: bool,
    pub reversed_lines: bool,
    pub block: Option<u16>,
    pub gate_phantom_positions: bool,
}

How the module’s pixels are wired into the card’s scan-line buffer (record 0x03). The vendor corpus shows two knobs beyond geometry.

Fields

reversed_groups: bool

Data groups (stored height / scan of them) in reverse order in the buffer, the vendor default (234 of 241 two-group configs).

reversed_lines: bool

Scan lines addressed bottom-up (scan-1-row) instead of top-down.

block: Option<u16>

Columns per run of the shift chain before it switches data group: [lower 0..b][upper 0..b][lower b..2b].... Default (module width) gives each group one contiguous half; the bench panel’s own file uses 64.

gate_phantom_positions: bool

Displace line positions width..2*width off the chain via the void-line column table; otherwise the card drives them with a fixed pattern that shows as a floor at black (docs/rendering.md). Off reproduces the factory image.

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 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.
