Struct ToneCode 

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

Validated tone code (index into CTCSS_FREQUENCIES).

Wraps a u8 index in the range 0..=50. Indices 0-49 are standard CTCSS sub-audible tones. Index 50 is the 1750 Hz tone burst used for European repeater access — it is NOT a CTCSS tone but a short audio-frequency burst. Confirmed by ARFC-D75 decompilation.

Use ToneCode::frequency_hz to look up the corresponding frequency.

Implementations

impl ToneCode

pub const MAX_INDEX: u8 = 50

Maximum valid tone code index (inclusive).

pub const fn new(index: u8) -> Result<Self, ValidationError>

Creates a new ToneCode from a raw index.

Errors

Returns ValidationError::ToneCodeOutOfRange if index > 50.

pub const fn index(self) -> u8

Returns the raw index into the CTCSS frequency table.

pub const fn frequency_hz(self) -> f64

Returns the CTCSS frequency in Hz for this tone code.

Trait Implementations

impl Clone for ToneCode

fn clone(&self) -> ToneCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToneCode

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

Formats the value using the given formatter.

impl Default for ToneCode

fn default() -> ToneCode

Returns the “default value” for a type.

impl Display for ToneCode

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

Formats the value using the given formatter.

impl Hash for ToneCode

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

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 ToneCode

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