func PatchValue ¶

func PatchValue(v reflect.Value) reflect.Value

PatchValue enables assignment to an unexported struct field by clearing the internal read-only flags.

It takes a reflect.Value and returns the same Value after patching. This allows the caller to call Set on a Value that originally pointed to an unexported field.

WARNING:

• This function relies on unsafe access to reflect.Value's internal 'flag' field.
• It is highly version-dependent and may break in future Go releases.
• Using this in production code is unsafe and may cause undefined behavior.
• Only use this in controlled internal tools where performance or testing requires it.
