Struct MicroCartridge 

pub struct MicroCartridge { /* private fields */ }

This struct represents an emulated Microdrive tape cartridge.

It consist of up to MAX_SECTORS Sectors. Instances of this struct can be “inserted” into one of 8 ZxMicrodrives’s emulator drives.

Implementations

impl MicroCartridge

pub fn head_at(&self) -> f32

Returns the current drive’s head position counted in sectors as floating point value.

The fractional part indicates how far the head position is within a sector.

pub fn max_sectors(&self) -> usize

Returns the number of the emulated physical sectors on the tape.

pub fn count_formatted(&self) -> usize

Returns the number of formatted sectors.

pub fn iter_with_indices( &self, ) -> FilterMap<Enumerate<Zip<Iter<'_, Sector>, Iter<'_, u32, Lsb0>>>, &dyn Fn((usize, (&Sector, BitRef<'_, Const, u32>))) -> Option<(u8, &Sector)>>

Returns an iterator of formatted sectors with their original indices.

pub fn is_write_protected(&self) -> bool

Returns true if the cartridge is write protected.

pub fn set_write_protected(&mut self, protect: bool)

Changes the write protected flag of the cartridge.

pub fn is_sector_formatted(&self, sector: u8) -> bool

Returns true if the given sector is formatted.

Panics

Panics if sector equals to or is above the max_sectors limit.

pub fn new_with_sectors<S>( sectors: S, write_protect: bool, max_sectors: usize, ) -> MicroCartridge

where S: Into<Vec<Sector>>,

Creates a new instance of MicroCartridge with provided sectors.

Note

Content of the sectors is not verified and is assumed to be properly formatted.

Panics

The number of sectors provided must not be greater than MAX_USABLE_SECTORS. max_sectors must not be 0 and must be grater or equal to the number of provided sectors and must not be greater than MAX_SECTORS.

pub fn new(max_sectors: usize) -> MicroCartridge

Creates a new instance of MicroCartridge with custom max_sectors number.

Panics

max_sectors must not be 0 and must not be greater than MAX_SECTORS.
