Struct Passcode 

pub struct Passcode(/* private fields */);

27-bit Matter setup passcode (Matter Core Spec §5.1.7).

Constructors enforce the 27-bit range and exclude the disallowed-trivial values from spec §5.1.7.1. The standard test passcode 20_202_021 is permitted.

Implementations

impl Passcode

pub fn new(value: u32) -> Result<Self>

Construct a setup passcode, enforcing Matter Core Spec §5.1.7.1: the value SHALL be in 1..=99_999_998 (MAX_PASSCODE) and MUST NOT be one of the trivial values in DISALLOWED_PASSCODES.

The wire field is 27 bits, but a value above MAX_PASSCODE (up to 2^27 - 1) is not a valid passcode — a setup code carrying one is rejected by every spec-compliant commissioner, so we reject it here rather than emit or accept an uncommissionable code.

Errors

Returns Error::PasscodeDisallowedTrivial if value is one of the spec-disallowed values in DISALLOWED_PASSCODES (this includes 0). Returns Error::PasscodeOutOfRange if value > MAX_PASSCODE.

pub const fn as_u32(self) -> u32

The passcode as a raw u32 in the range 0..1 << 27.
