Extension trait for Option types to convert to Result with DecrustError

This trait provides methods to convert an Option to a Result, with a MissingValue error if the Option is None.

This trait is object-safe and can be used with dynamic dispatch.

Required Methods

fn decrust_ok_or_missing_value( self, item_description: &str, ) -> Result<T, DecrustError>

Converts an Option to a Result, with a MissingValue error if None

Parameters

• item_description - Description of the missing value for the error message

Returns

Ok(value) if the Option is Some(value), Err(DecrustError::MissingValue) otherwise

fn decrust_ok_or_missing_value_owned( self, item_description: String, ) -> Result<T, DecrustError>

Converts an Option to a Result, with a MissingValue error if None (owned string version)

Parameters

• item_description - Description of the missing value for the error message

Returns

Ok(value) if the Option is Some(value), Err(DecrustError::MissingValue) otherwise
