Function match_result_code

Source 
pub fn match_result_code<F, T>(result_code: i32, on_success: F) -> Result<T>
where
    F: FnOnce() -> T,
Expand description

Evaluates a result code and executes a closure on success (result_code > 0).

§Arguments

  • result_code - An integer representing the operation result code
  • on_success - A closure that will be executed if result_code > 0

§Type Parameters

  • F - The type of the closure
  • T - The return type of the closure

§Returns

Returns a Result<T> where:

  • Ok(T) - Contains the value returned by the closure if result_code > 0
  • Ok(None) - If result_code == 0 (no data/empty result)
  • Err(Error) - For negative result codes

§Note

This function treats 0 as a valid “no data” state and positive values as success.
