Enum MappedAddr 

pub enum MappedAddr {
    Rom(u32),
    Sram(u32),
    Coprocessor,
    Open,
}

The result of a board’s address decode: where a 24-bit CPU address lands.

The bus uses this to route a read/write to the right backing store, and the default Board::read24 / Board::write24 consume it directly over the board’s own storage.

Variants

Rom(u32)

Maps into ROM at the given linear byte offset (already mirror-folded to rom_size).

Sram(u32)

Maps into cartridge SRAM at the given offset (already wrapped to sram_size).

Coprocessor

Maps into a coprocessor register window (the board handles it internally).

Open

Open bus / unmapped (returns the last bus value).

Trait Implementations

impl Clone for MappedAddr

fn clone(&self) -> MappedAddr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MappedAddr

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

Formats the value using the given formatter.

impl PartialEq for MappedAddr

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