Struct pretty_error_debug::Wrapper

pub struct Wrapper<E: Error + 'static>(_);

Instead of adding a new type, you can simply use this wrapper

Example

use some_external_mod::{SomeError, some_test};

fn main() -> Result<(), pretty_error_debug::Wrapper<SomeError>> {
    some_test()?;
    Ok(())
}

mod some_external_mod {
    #[derive(Debug)]
    pub struct SomeError;

    impl std::error::Error for SomeError {}

    impl std::fmt::Display for SomeError {
        fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
            f.write_str("Something went wrong")
        }
    }

    pub fn some_test() -> Result<(), SomeError> {
        Err(SomeError)
    }
}

Trait Implementations

impl<E: Clone + Error + 'static> Clone for Wrapper<E>

fn clone(&self) -> Wrapper<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Error + 'static> Debug for Wrapper<E>

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

Formats the value using the given formatter.

impl<E: Default + Error + 'static> Default for Wrapper<E>

fn default() -> Wrapper<E>

Returns the “default value” for a type.

impl<E: Error + 'static> Display for Wrapper<E>

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

Formats the value using the given formatter.

impl<E: Error + 'static> Error for Wrapper<E>

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

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

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

fn provide<'a>(&'a self, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl<E: Error + 'static> From<E> for Wrapper<E>

fn from(value: E) -> Self

Converts to this type from the input type.

impl<E: Copy + Error + 'static> Copy for Wrapper<E>
