zk server failed

When I use zk server,it returns failed, I used rust 1.66 1.70 1.72 1.74 1.75 1.76 How to compile success?

Try rust 1.77.1 (7cf61ebde 2024-03-27), it works on my machine.

1. Error about [u8] not being Sized: You’re trying to use an array slice (&[u8]) in a way that requires its size to be known at compile time, but Rust doesn't know the size of slices ahead of time. To fix this, make sure the function Address::from_slice is expecting a slice (&[u8]) instead of an array. If you can edit Address::from_slice, change its parameter to accept a slice. The corrected function would look something like:

rust Copy code impl Address { pub fn from_slice(slice: &[u8]) -> Self { // Implementation goes here } } And you’d use it like this in your map:

rust Copy code .map(|account| (start_account, Address::from_slice(account)))

2. Error about needing type annotations for Vec: When you initialize a vector with Vec::new(), Rust needs to know what type of elements it will hold. If the type isn't specified elsewhere, you need to declare it when creating the vector. For example, if your vector is supposed to hold integers:

rust Copy code let mut account_diff: Vec = Vec::new(); This specifies that account_diff will hold values of type u32.

3. Error about no field from_block: This error means you're trying to access a field (from_block) that Rust doesn't recognize for the given data type. Double-check the type of the variable op. Ensure it’s the correct type that should have the from_block field. If op is indeed the correct type but still causing errors, there might be an issue with how it’s defined or used.

4. Warnings about unused imports: Rust is telling you that you've imported some modules or functions (ToBigInt, ToPrimitive) that you're not using anywhere in your code. You can safely remove these imports to clean up your code:

rust Copy code // Remove or comment out these lines // use num::bigint::ToBigInt; // use num::ToPrimitive; If any of these issues persist after you make changes, try running cargo check to get a quick overview of errors without compiling the whole project. This can help you catch issues faster.
