macro_rules! implement_error_in_enum {
    ($enum_error:ident, $err_type: path, $enum_variant: path) => { ... };
}

Implement the From trait for an enum.

WARNING: you might prefer to use thiserror instead of this macro.

Params

    implement_error_in_enum!($type_, $err_type, $enum_variant);

Example

 use std::fmt::Debug;
 use std::io::Error;
 use heimdall_errors::implement_error_in_enum;


 pub (crate) enum EnumError {
     IO(Error)
 }


 // Implement From<Error> for StructError.
 implement_error_in_enum!(EnumError, Error, EnumError::IO);

Code generated

The code

implement_error_in_enum!(EnumError, Error, EnumError::IO);

generates the next code

 impl From<Error> for EnumError {
    fn from(err: Error) -> Self {
        EnumError::Io(err)
     }
 }
