structure help

Hello all

Could anyone tell me what the ": 1" is doing in this instance? I haven't managed to find it anywhere on here so far.

Thanks

    struct structurename {
      uint32_t variable : 1;
    } PACKED;

ignore this.

I have found something.

my understanding if I have multiple uint32_t variable with : 1, they are represented as a bool and packed into a uint32_t
