How to upgrade Leptos

1. Open Cargo.toml. It should show something like the following code: ``` [workspace]

[package] name = "stories52" …

[lib] crate-type = ["cdylib", "rlib"]

[dependencies] leptos = { version = "0.4.9", default-features = false, features = [ "serde", ] } leptos_actix = { version = "0.4.9", optional = true } leptos_meta = { version = "0.4.9", default-features = false } leptos_router = { version = "0.4.9", default-features = false } …

2. Modify manually the version for the following libraries:
  - leptos
  - leptos_actix
  - leptos_meta
  - leptos_router
3. Make sure you have the latest version of RustRust
Basic Concepts



Creating an Array



let arr: Vec<String> = vec!["example".to_string()];





  Array of objects





pub struct Book {

  pub id: u16,

  pub title: String,

}



...



let arr: Vec<Sto...: `rustup update`
4. Run `cargo build`.

### Example

Before:

futures = "0.3" gloo-net = { version = "0.2", features = ["http"] } leptos = { version = "0.4.9", default-features = false, features = [ "serde", ] } leptos_actix = { version = "0.4.9", optional = true } leptos_meta = { version = "0.4.9", default-features = false } leptos_router = { version = "0.4.9", default-features = false } log = "0.4"

After:

futures = "0.3" gloo-net = { version = "0.2", features = ["http"] } leptos = { version = "0.5.0-rc2", default-features = false, features = [ "serde", ] } leptos_actix = { version = "0.5.0-rc2", optional = true } leptos_meta = { version = "0.5.0-rc2", default-features = false } leptos_router = { version = "0.5.0-rc2", default-features = false } log = "0.4" ```
