Error message "recursive type is not allowed for public state variables" causes confusion

[haoyang9804]

Description

The following code snippet causes an error with message recursive type is not allowed for public state variables. I cannot find references to "recursive type" in the doc https://docs.soliditylang.org/en/latest/types.html. Can we improve the doc or the error message

contract contract0 {
  struct struct1 {
    mapping(int64 => int64)[10] array2;
  }
  mapping(int64 => struct1) public mapping11;
}

Environment

• Compiler version: 0.8.29
