[jira] [Created] (ARROW-7086) [C++] Provide a wrapper for invoking
factories to produce a Result
Ben Kietzman created ARROW-7086:
-----------------------------------
Summary: [C++] Provide a wrapper for invoking factories to produce a Result
Key: ARROW-7086
URL: https://issues.apache.org/jira/browse/ARROW-7086
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Affects Versions: 0.15.1
Reporter: Ben Kietzman
Assignee: Ben Kietzman
Fix For: 1.0.0
There is a proliferation of code like:
{code}
Result<int> SafeAdd(int a, int b) {
int out;
RETURN_NOT_OK(DoSafeAdd(a, b, &out));
return out;
}
{code}
Ideally, this should be resolved by moving the implementation of SafeAdd into the Result returning function then using {{Result::Value}} in the Status returning function. In cases where this is inconvenient, it'd be helpful to have an adapter for doing this more efficiently:
{code}
Result<int> SafeAdd(int a, int b) {
return ResultInvoke(DoSafeAdd, a, b);
}
{code}
