Variable

Stylistic Conventions

  • Names of variables are in lower case.

  • Word separation can be indicated by underscores (‘_’), but use of underscores is discouraged unless the name would be hard to read otherwise.

  • Names of Types and Modules begin with a capital letter and word separation is shown with upper camel case instead of underscores.

  • Names of functions and macros are in lower case, without underscores.

  • Functions that write to their arguments have names that end in !. These are sometimes called “mutating” or “in-place” functions because they are intended to produce changes in their arguments after the function is called, not just return a value.
