根因分析

函数期望接收指向类型的指针 (*T)，但传入了非指针值 (T)，导致类型不匹配。

English

A function expects a pointer to a type (*T) but receives a non-pointer value (T), causing a type mismatch.

解决方案

  1. Pass the address of the variable: `functionName(&variable)` instead of `functionName(variable)`.
  2. If the variable is not addressable (e.g., map value), copy it first: `tmp := variable; functionName(&tmp)`.

无效尝试

常见但无效的做法:

  1. 70% 失败

    Casting requires the value to be addressable; this often leads to another compilation error.

  2. 60% 失败

    Modifying library or external function signatures is not always possible or breaks other code.
