ownership	Ownership violations governed by use	RustBites Ownership
copy and move	primitive types are copied to new location, non-copy types are moved.	RustBites Data
basic functions	pass by value and by reference	RustBites Functions
helper functions	Illustrates displaying values and types using both concrete and generic functions with a useful set of helper functions.
closures	Closures are function objects that operate on parameters and captures of local data.	RustBites Functions
structs	struct with constructor and methods	RustBites structs
structs with defaults and clones	struct with derived default and clone and struct with defined default and clone	RustBites Generics and Traits
generic function and struct	displays type using std::any::type_name	RustBites traits
generic struct	generic struct with bounds	RustBites traits
struct copy and move	Illustrates use (and non-use) of derived Copy trait	RustBites Data
create many std::collection types	create and display arrays, tuples, structs, vecs, vecdeques, hashmaps, strings, and strs	RustBites Collections
str	basic str operations	RustBites Strings
String	basic String operations	RustBites Strings
iterating over strings	iterating over ASCII and non-ASCII strings	RustBites Iterators
String, str compares	Equality comparison between strings using == operator
string conversions	convert between String, &str, PathBuf, &Path	RustBites conver
lifecycle using Box	uses TestLifeCycle instance installed in Box to illustrate lifecycle and use of heap	RustBites LifeCycle
functions accepting iterator	explicit use of iterator in loop, implicit use with for loop	RustBites Iterators
iterator for custom type	custom type returns iterator over owned collection	RustBites Iterators
custom iterator	implement custom iterator for custom type	RustBites Iterators
interation over collections	iterating over array, String, Vec, VecDeq, and HashMap	RustBites Iterators RustBites DataStr
into_iter	compares iter() with into_iter()	RustBites Iterators
custom enumertion	illustrates matching with custom enumeration	RustBites Enum
non-enum matching	matching chars: digit, lower case, uppercase, all else	RustBites Enum
file error handling	open for read, write, and read to string	RustBites ErrHand
error bubbling	illustrates file operations with error bubbling. The ErrHand link at the right explains how the bubbling process works using the "?" try operator.	RustBites ErrHand
Lifetimes	Result and Option wrapping &str so need lifetime annotation	RustBites lifetime RustBites options
plugin architecture	plugin host holds Option of mutable reference to plugin - needs annotation. See options link at right for context: why you might chose this architecture.	RustBites options
host owns plugin	eliminate lifetime annotations in plugin architecture by moving plugin into host. See options link at right for advantages of host ownership.	RustBites options
RegEx matching	basic matching examples	RustBites regex
RegEx Operations	match, find, find_iter, and captures	RustBites regex
interior mutability	illustrates non-lexical scope analysis and run-time borrow checking with RefCell<T>	RustBites Safety
interior mut with std::cell::Cells	demos that show mutations with Cell<T> and RefCell<T>	RustBites smartptrs
Basic Threads	two threads mutably sharing atomic usize and std::output	RustBites threads
sharing non-thread-safe value protected by Mutex<T>	main and two child threads mutably sharing a string	RustBites threads
ThreadResult<T>	ThreadResult<T> is similar to C++ future: no hooks into async runtime. See link at right for details.	RustBites threads
