How add inputs to vector?

[hanusek]

Hello! I have a problem with generics in Rust. I would like to add input to the vector.

Example 1:

[..]
let d_in1 = gpiod.pd7.into_floating_input(&mut gpiod.crl);
let d_in2 = gpiod.pd6.into_floating_input(&mut gpiod.crl);
let v = [d_in1, d_in2];

Error:

    |
200 |                 let v = [d_in1, d_in2];
    |                                 ^^^^^ expected `7`, found `6`
    |
    = note: expected struct `stm32f1xx_hal::gpio::Pin<_, _, 7>`
               found struct `stm32f1xx_hal::gpio::Pin<_, _, 6>`

Example 2:

[...]
let d_in1 = gpiod.pd7.into_floating_input(&mut gpiod.crl);
let d_in2 = gpiod.pd6.into_floating_input(&mut gpiod.crl);

let v = heapless::Vec::new();
v.push(d_in1);
v.push(d_in2);

Error:

203 |                 v.push(d_in1);
    |                 -      ----- this argument has type `stm32f1xx_hal::gpio::Pin<'D', 7>`...
    |                 |
    |                 ... which causes `v` to have type `Vec<stm32f1xx_hal::gpio::Pin<'D', 7>, _>`

    |                        this argument influences the return type of `push`

How to fix it?

this is not an issue in embedded-hal, you should ask in the stm32f1xx-hal issue tracker
