Enum NakReason 

#[non_exhaustive]
pub enum NakReason {
    InvalidCommand,
    WrongMode,
    CommandTooLong,
    DataIncorrect,
    BufferFull,
    Unknown {
        code: u8,
    },
}

NAK response reason code.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidCommand

The command byte is not recognised.

WrongMode

The modem is in the wrong mode for this command.

CommandTooLong

The command frame exceeds the maximum length.

DataIncorrect

The command payload contains incorrect data.

BufferFull

The TX buffer is full.

Unknown

Unknown NAK reason byte — the raw code is preserved.

Fields

code: u8

Raw byte as received from the modem.

Implementations

impl NakReason

pub const fn from_byte(b: u8) -> NakReason

Parse a raw reason byte. Never fails — unknown codes are captured as NakReason::Unknown.

Trait Implementations

impl Clone for NakReason

fn clone(&self) -> NakReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NakReason

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

Formats the value using the given formatter.

impl Hash for NakReason

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NakReason

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