在 rust 中，如何聲明 3 struct 類型數組的別名？

Question

有

pub struct Cell {
    coord: Coord,
    content: ValidMoves,
}

如何將“類型”（類型、枚舉、結構）聲明為 3 個Cell的數組？

就像是

pub type Row: [Cell, 3] = [ Cell, Cell, Cell ];

我也試過

pub type Row = [Cell, 3];

Answer 1

解決了 ！！

pub type Row = [Cell; 3];

我找到了正確的解決方案閱讀編譯器 output

error: expected one of `!`, `(`, `+`, `::`, `;`, `<`, or `]`, found `,`
  --> src\game\structs.rs:56:21
   |
56 | pub type Row = [Cell, 3];
   |                     ^ expected one of 7 possible tokens
