#6 – minised, part 1

Use Rust to develop a miniature version of the “sed” command-line utility, part 1. Covers topics that include a subset of functionality for the “sed” command-line utility that’s used for replacing text, the scope of features that we’ll include in the miniature “sed” utility that we’re building, how to define a “struct” in Rust, how to leverage the “Option” enum for a value that may be either something or nothing, how to instantiate a “struct” in Rust via an associated function in an implementation block, how to bring a “struct” into scope in the binary crate, and how to use the “unwrap_or_else” method on a “Result” enum and define a “closure”.
