Enum GreeterError 

#[non_exhaustive]
pub enum GreeterError {
    CommunicationError,
    ConnectionFailed,
    SessionFailed,
    NoAutologin,
    InvalidUser,
}

Error codes returned by greeter operations.

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.

CommunicationError

error communicating with daemon.

ConnectionFailed

failed to connect to the daemon.

SessionFailed

requested session failed to start.

NoAutologin

autologin not configured.

InvalidUser

autologin not configured.

Trait Implementations

impl Clone for GreeterError

fn clone(&self) -> GreeterError

Returns the quark identifying the error domain.

fn code(self) -> i32

Gets the integer representation of the variant.

fn from(code: i32) -> Option<Self>

Tries to convert an integer code to an enum variant.

impl From<GreeterError> for Value

fn from(v: GreeterError) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for GreeterError

type Checker = GenericValueTypeChecker<GreeterError>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for GreeterError

type ParamSpec = ParamSpecEnum

type SetValue = GreeterError

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str, GreeterError) -> ParamSpecEnumBuilder<'_, GreeterError>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for GreeterError

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 Ord for GreeterError

fn cmp(&self, other: &GreeterError) -> 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 GreeterError

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

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.

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for GreeterError

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for GreeterError

type Type = GreeterError

Type to get the Type from.

impl Copy for GreeterError
