Module prelude

Frequently used types and traits.

This module contains the most common types and traits to import. Here is an idiomatic way to import the prelude:

use starina_api::prelude::*;

let mut v = Vec::new();
v.push(1);

What’s in the prelude?

Since Starina apps are #![no_std] crates, this prelude includes types from alloc so that experienced Rust programmers can use familiar types without asking “Where is Vec?”.

Why should I use the prelude?

You don’t have to use the prelude. However, it’s a convenient way to reduce the number of your keystrokes.

Modules

• vec
  A contiguous growable array type with heap-allocated contents, written Vec<T>.

Macros

• debug
  Logs with LogLevel::Debug.
• debug_warn
  Similar to warn!, but only logs in debug mode.
• error
  Logs with LogLevel::Error.
• format
  Creates a String using interpolation of runtime expressions.
• info
  Logs with LogLevel::Info.
• trace
  Logs with LogLevel::Trace.
• vec
  Creates a Vec containing the arguments.
• warn
  Logs with LogLevel::Warn.

Structs

• Box
  A pointer type that uniquely owns a heap allocation of type T.
• String
  A UTF-8–encoded, growable string.
• Vec
  A contiguous growable array type, written as Vec<T>, short for ‘vector’.

Traits

• ToOwned
  A generalization of Clone to borrowed data.
• ToString
  A trait for converting a value to a String.
