Struct GroupSubject 

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

A validated group subject string.

WhatsApp limits group subjects to GROUP_SUBJECT_MAX_LENGTH characters.

Implementations

impl GroupSubject

pub fn new(value: impl Into<String>) -> Result<GroupSubject, Error>

Create a new validated string, returning an error if it exceeds the maximum length.

pub fn new_unchecked(value: impl Into<String>) -> GroupSubject

Create a new string without validation (for parsing responses).

pub fn as_str(&self) -> &str

Get the string as a slice.

pub fn into_string(self) -> String

Consume self and return the inner string.

Trait Implementations

impl AsRef<str> for GroupSubject

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for GroupSubject

fn clone(&self) -> GroupSubject

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GroupSubject

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

Formats the value using the given formatter.

impl Display for GroupSubject

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

Formats the value using the given formatter.

impl Hash for GroupSubject

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 GroupSubject

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