Enum MappedRead

pub enum MappedRead {
    Bus,
    Chr(usize),
    CIRam(usize),
    ExRam(usize),
    PrgRom(usize),
    PrgRam(usize),
    Data(u8),
}

Type of read operation for an address for a given Mapper.

Variants

Bus

Defer to default data bus behavior for this read. Primarily used to read from a mirrored Console-Internal RAM (i.e Nametable) address.

Chr(usize)

Read from a CHR ROM or RAM address.

CIRam(usize)

Read from a non-mirrored Console-Internal RAM (i.e. Nameteable) address for Mappers that support custom Nametable Mirroring.

ExRam(usize)

Read from an External RAM address for Mappers that support EXRAM.

PrgRom(usize)

Read from a PRG ROM address.

PrgRam(usize)

Read from a PRG ROM address.

Data(u8)

Provide data directly for this read (i.e. from an internal Mapper register).

Trait Implementations

impl Clone for MappedRead

fn clone(&self) -> MappedRead

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MappedRead

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MappedRead

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MappedRead

fn eq(&self, other: &MappedRead) -> 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 MappedRead

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
