Struct CidResponse 

pub struct CidResponse {
    pub raw: [u8; 16],
}

CID register (CMD2/CMD10 response). Identifies the card’s manufacturer, product, serial number, and manufacturing date.

Field layout follows SD Physical Layer spec section 5.2; only SD cards are decoded here. eMMC uses a different field layout and is not supported.

Fields

raw: [u8; 16]

Implementations

impl CidResponse

pub fn from_raw(raw: [u8; 16]) -> Self

pub fn manufacturer_id(&self) -> u8

Manufacturer ID (MID) — 8-bit code assigned by the SD Association.

pub fn oem_id(&self) -> [u8; 2]

OEM/Application ID (OID) — two ASCII characters identifying the card OEM. Returned as a [u8; 2]; bytes outside printable ASCII are preserved verbatim so callers can detect non-conforming firmware.

pub fn product_name(&self) -> [u8; 5]

Product name (PNM) — 5 ASCII characters.

pub fn product_revision(&self) -> (u8, u8)

Product revision (PRV) as a (major, minor) pair, both 4-bit BCD.

pub fn serial_number(&self) -> u32

Product serial number (PSN) — 32-bit big-endian.

pub fn manufacture_date(&self) -> (u16, u8)

Manufacturing date as (year, month) where year is the absolute 4-digit year (SD spec offsets year by 2000).

Layout: bits 19:8 of bytes 13..=14 hold the date — 12 bits split as year (8 bits) and month (4 bits).
