Struct dbus_tree::MethodErr

pub struct MethodErr(_, _);

A D-Bus Method Error, containing an error name and a description.

Unlike the "Error" struct, this is a Rust native struct.

Implementations

impl MethodErr

pub fn invalid_arg<T>(a: &T) -> MethodErr where
    T: Debug + ?Sized, 

Create an Invalid Args MethodErr.

pub fn no_arg() -> MethodErr

Create a MethodErr that there are not enough arguments given.

pub fn failed<T>(a: &T) -> MethodErr where
    T: Display + ?Sized, 

Create a MethodErr that the method failed in the way specified.

pub fn no_path<T>(a: &T) -> MethodErr where
    T: Display + ?Sized, 

Create a MethodErr that the Object path was unknown.

pub fn no_interface<T>(a: &T) -> MethodErr where
    T: Display + ?Sized, 

Create a MethodErr that the Interface was unknown.

pub fn no_method<T>(a: &T) -> MethodErr where
    T: Display + ?Sized, 

Create a MethodErr that the Method was unknown.

pub fn no_property<T>(a: &T) -> MethodErr where
    T: Display + ?Sized, 

Create a MethodErr that the Property was unknown.

pub fn ro_property<T>(a: &T) -> MethodErr where
    T: Display + ?Sized, 

Create a MethodErr that the Property was read-only.

pub fn errorname(&self) -> &ErrorName<'static>

Error name accessor

pub fn description(&self) -> &str

Description accessor

pub fn to_message(&self, msg: &Message) -> Message

Creates an error reply from a method call message.

Note: You normally don't need to use this function, as it is called internally from Tree::handle.

Trait Implementations

impl Clone for MethodErr

fn clone(&self) -> MethodErr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MethodErr

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

Formats the value using the given formatter.

impl Display for MethodErr

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

Formats the value using the given formatter.

impl Eq for MethodErr

impl Error for MethodErr

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

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

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<T, M> From<(T, M)> for MethodErr where
    M: Into<String>,
    T: Into<ErrorName<'static>>, 

fn from((T, M)) -> MethodErr

Performs the conversion.

impl From<Error> for MethodErr

fn from(t: Error) -> MethodErr

Performs the conversion.

impl From<TypeMismatchError> for MethodErr

fn from(t: TypeMismatchError) -> MethodErr

Performs the conversion.

impl Ord for MethodErr

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

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<MethodErr> for MethodErr

fn eq(&self, other: &MethodErr) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &MethodErr) -> bool

This method tests for !=.

impl PartialOrd<MethodErr> for MethodErr

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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