Struct Command 

pub struct Command {
    pub index: u8,
    pub argument: u32,
    pub response: ResponseType,
}

SD/SDIO/MMC command packet submitted on the CMD line.

Fields

index: u8

argument: u32

response: ResponseType

Implementations

impl Command

pub const fn new(index: u8, argument: u32, response: ResponseType) -> Self

pub const fn index(self) -> u8

pub const fn argument(self) -> u32

pub const fn with_response(self, response: ResponseType) -> Self

pub const fn with_resp_type(self, response: ResponseType) -> Self

Return a copy of this command with its response type overridden.

Kept as a compatibility alias for existing SD/MMC protocol helpers.

pub const fn cmd(self) -> u8

Compatibility alias for older SD/MMC command helpers.

pub const fn arg(self) -> u32

Compatibility alias for older SD/MMC command helpers.

pub const fn data_direction(&self) -> Option<DataDirection>

Direction of the data phase that follows this command when it is unambiguous from the command index alone.

SDIO CMD53 carries its direction in the argument; CMD6 is also overloaded between ACMD6 and SWITCH_FUNC, so both return None.

pub const fn data_block_size(&self) -> Option<u32>

Size in bytes of the data block when fixed by the command index.

pub fn crc7(&self) -> u8

Compute the SD SPI-mode CRC7 for this command packet.

pub fn to_spi_bytes(&self) -> [u8; 6]

Build the 6-byte SD SPI command packet.

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Command

impl Debug for Command

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

Formats the value using the given formatter.

impl Eq for Command

impl PartialEq for Command

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