Enum RegistrationState 

#[repr(u8)]
pub enum RegistrationState {
    NotRegisteredAndDisabled = 0,
    RegisteredHome = 1,
    NotRegisteredSearching = 2,
    RegistrationDenied = 3,
    Unknown = 4,
    RegisteredRoaming = 5,
}

The current registration state of the modem (from AT+CREG).

Modems have to be ‘registered’ (i.e. connected to) a given cellular network to be able to do anything useful (text, call, etc.). Therefore, checking the registration state can be useful to figure out why your modem isn’t working.

Variants

NotRegisteredAndDisabled = 0

Not registered, and not searching for a new operator at present.

RegisteredHome = 1

Registered, and on our ‘home’ network (i.e. not roaming)

NotRegisteredSearching = 2

Not registered, and searching for a new operator.

RegistrationDenied = 3

Registration denied.

Unknown = 4

Registration state unknown.

RegisteredRoaming = 5

Reigstered, and on a ‘roaming’ network.

Implementations

impl RegistrationState

pub fn is_registered(&self) -> bool

If the RegistrationState is either RegisteredHome or RegisteredRoaming, returns true. Otherwise, returns false.

Trait Implementations

impl Fail for RegistrationState

fn name(&self) -> Option<&str>

Returns the “name” of the error.

fn cause(&self) -> Option<&dyn Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Converts an i8 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i16(n: i16) -> Option<Self>

Converts an i16 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i32(n: i32) -> Option<Self>

Converts an i32 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i128(n: i128) -> Option<Self>

Converts an i128 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_usize(n: usize) -> Option<Self>

Converts a usize to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_u8(n: u8) -> Option<Self>

Converts an u8 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_u16(n: u16) -> Option<Self>

Converts an u16 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_u32(n: u32) -> Option<Self>

Converts an u32 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_u128(n: u128) -> Option<Self>

Converts an u128 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_f32(n: f32) -> Option<Self>

Converts a f32 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_f64(n: f64) -> Option<Self>

Converts a f64 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

impl Ord for RegistrationState

fn cmp(&self, other: &RegistrationState) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RegistrationState

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

impl PartialOrd for RegistrationState

fn partial_cmp(&self, other: &RegistrationState) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
