Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “rustup is the toolchain manager that includes the compiler and Cargo’s package manager.”

A block of code is set as follows:

pub struct Block {
    timestamp: i64,
    pre_block_hash: String,
    hash: String,
    transactions: Vec<Transaction>,
    nonce: i64,
    height: usize,
}

Any command-line input or output is written as follows:

brew install rustup

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Working with strings is straightforward in Rust, so it’s important to know the difference between the String type and string literals.”
