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: "The template for our application image can be defined in a Dockerfile file in the root of our application next to our Cargo.toml file."
A block of code is set as follows:
RUN apt-get update -yqq && apt-get install -yqq cmake g++ RUN cargo install diesel_cli --no-default-features --features postgres
Any command-line input or output is written as follows:
echo DATABASE_URL=postgres://username:password@postgres/to_do > .env
Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: " We can see that it has been updated (PUSHED) in the last 2 minutes."
