Expand description

Utility methods for the WAGon suite of libraries.

Provides a number of simple functions, as well as a trait version of std::iter::Peekable and a fallible version of itertools::Itertools.

Macros§

ConversionError: We failed to convert from some thing to another thing.
SplitError: An struct for when split_to_twople fails.
UnexpectedEnd: Error struct to represent we’ve reached the end of an iterator. Used for ResultNext.

ErrorReport: A trait for Errors that return a specific message and span structure.
FallibleItertools: A slightly modified version of the Itertools trait which returns Result instead.
Peek: A trait version of the functionality that Peekable provides.
ResultNext: Quickly get a result from an iterator of Results.
ResultPeek: Same as ResultNext but for things that implement Peek.
Spannable: Trait for objects that provide Span information. Used for error messaging.
UnsafeNext: Forcibly extract an item out of an iterator of Results.
UnsafePeek: Same as UnsafeNext but intended for iterators that allow peeking (such as Peekable).

comma_separated: Given a list of objects that implement std::fmt::Display. Returns a comma separated string.
comma_separated_with_or: Given a vector of strings, return a string that has all the values joined by a ,. Except for the last which is joined by or.
comma_separated_with_or_str: Same as comma_separated_with_or, but takes a vector of &str instead.
normalize_to_probabilities: Given a list of values, attempt to normalize them based on their sum.
rem_first_and_last_char: Removes the first and last character of a string.
rem_first_char: Removes the first character of a string.
rem_first_char_n: Removes the first n characters of a string.
rem_last_char: Removes last character of a string.
remove_whitespace: Removes all whitespace from a string.
split_to_twople: Given string and a character. Attempt to split the string at that character into 2 distinct parts.
