Struct DtmfDigits 

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

DTMF digit sequence (valid characters: 0-9, A-D, *, #).

The maximum length of a DTMF digit sequence on the TH-D75 is 16 characters.

Implementations

impl DtmfDigits

pub const MAX_LEN: usize = 16

Maximum length of a DTMF digit sequence.

pub fn new(digits: &str) -> Option<Self>

Creates a new DTMF digit sequence after validating all characters.

Errors

Returns None if the sequence exceeds 16 characters or contains invalid DTMF digits.

pub fn as_str(&self) -> &str

Returns the digit sequence as a string slice.

pub const fn len(&self) -> usize

Returns the number of digits in the sequence.

pub const fn is_empty(&self) -> bool

Returns true if the digit sequence is empty.

Trait Implementations

impl Clone for DtmfDigits

fn clone(&self) -> DtmfDigits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DtmfDigits

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

Formats the value using the given formatter.

impl Default for DtmfDigits

fn default() -> DtmfDigits

Returns the “default value” for a type.

impl Hash for DtmfDigits

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 DtmfDigits

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