Done :)

Relevant: (not sure if need to be done in this PR though)

internal/compiler/lexer.rs:            // Once MSRV is 1.91
internal/compiler/passes/repeater_component.rs:        // Could use Vec::extract_if if MSRV >= 1.87
internal/compiler/translations.rs:        // slice::trim_ascii_start when MSRV >= 1.80
internal/core/graphics/color.rs:// until slint uses rust 1.90 as MSRV.
docs/building.md:have Rust installed, make sure that it's at least version 1.88 or newer. You can check which version you have installed

The rust-version of the helper crate is not using the workspace and so may block cargo update (I don't know if this is a problem or not)

[ogoffart]

Please also update the instance in docs/building.md

I've upgraded all the places in the code you mentioned.

@expenses Do you remember what you meant with this?

// until slint uses rust 1.90 as MSRV.
const fn round(mut value: f32) -> u8 {
    if value % 1.0 > 0.5 {
        value += 0.5;
    }

    value as _
}

https://doc.rust-lang.org/std/primitive.f32.html#method.round f32::round was only made const in 1.90

Thanks. I've now replaced round(value * 255.0) with (value * 255.0).round() as u8
