Modules

__std_iter	Composable external iteration.
fmt	Utilities for formatting and printing Strings.
structs	The concrete iterator types.

Macros

debug	Logs a message at the debug level.
error	Logs a message at the error level.
info	Logs a message at the info level.
iproduct	Create an iterator over the “cartesian product” of iterators.
izip	Create an iterator running multiple iterators in lockstep.
log_enabled	Determines if a message logged at the specified level in that module will be logged.
trace	Logs a message at the trace level.
warn	Logs a message at the warn level.

Structs

BufReader	The BufReader struct adds buffering to any reader.
BufWriter	Wraps a writer and buffers its output.
DryRunOpt
File	A reference to an open file on the filesystem.
LoggingOpt
Problem	Wraps error, context and backtrace information and formats it for display. Data is heap allocated to avoid type parameters or lifetimes.

Enums

Diff	A type returned by the diff_with function.
Either	The enum Either with variants Left and Right is a general purpose sum type with two cases.
EitherOrBoth	Value that either holds a single A or B, or both.
FoldWhile	An enum used for controlling the execution of .fold_while().
MinMaxResult	MinMaxResult is an enum returned by minmax. See Itertools::minmax() for more detail.
Position	A value yielded by WithPosition. Indicates the position of this element in the iterator results.

Traits

Boolinator	This trait defines a number of combinator-style methods for use with bool values.
BufRead	A BufRead is a type of Reader which has an internal buffer, allowing it to perform extra ways of reading.
Debug	? formatting.
Display	Format trait for an empty format, {}.
FailedTo	Extension of Result that allows program to panic with Display message on Err for fatal application errors that are not bugs
FailedToIter	Convert Iterator of Result<O, E> to iterator of O and panic on first E with problem message
Itertools	An Iterator blanket implementation that provides extra adaptors and methods.
MapProblem	Map type containing error to type containing Problem
MapProblemOr	Map type not containing any error to type containing given Problem
OkOrLog	Extension of Result that allows program to log on Err with Display message for application errors that are not critical
OkOrLogIter	Convert Iterator of Result<O, E> to iterator of Option<O> and log any Err variants
OkOrProblem	Extension trait to map Option to Result with Problem
PeekingNext	An iterator that allows peeking at an element before deciding to accept it.
ProblemWhile	Convert to Problem if needed and add context to it
Read	The Read trait allows for reading bytes from a source.
StructOpt	A struct that is converted from command line arguments.
TapBooleanOps	Tap operations for bool.
TapOps	Tap operations for all types.
TapOptionOps	Tap operations for Option.
TapResultOps	Tap operations for Result.
Write	A trait for objects which are byte-oriented sinks.

Functions

assert_equal	Assert that two iterables produce equal sequences, with the same semantics as equal(a, b).
concat	Combine all an iterator's elements into one element by using Extend.
cons_tuples	Create an iterator that maps for example iterators of ((A, B), C) to (A, B, C).
diff_with	Compares every element yielded by both i and j with the given function in lock-step and returns a Diff which describes how j differs from i.
equal	Return true if both iterables produce equal sequences (elements pairwise equal and sequences of the same length), false otherwise.
in_context_of	Executes closure with problem_while context
in_context_of_with	Executes closure with problem_while_with context
init_logger
iterate	Creates a new iterator that infinitely applies function to value and yields results.
kmerge_by	Create an iterator that merges elements of the contained iterators.
multizip	An iterator that generalizes .zip() and allows running multiple iterators in lockstep.
partition	Partition a sequence using predicate pred so that elements that map to true are placed before elements which map to false.
process_results	“Lift” a function of the values of an iterator so that it can process an iterator of Result values instead.
read_stdin
repeat_call	Deprecated An iterator source that produces elements indefinitely by calling a given closure.
repeat_n	Create an iterator that produces n repetitions of element.
stdin	Constructs a new handle to the standard input of the current process.
stdout	Constructs a new handle to the standard output of the current process.
unfold	Creates a new unfold source with the specified closure as the "iterator function" and an initial state to eventually pass to the closure
