Rust: Finding dates in data-streams

#Rust pop-quiz answer to finding dates in data-streams.

You want a date? I got'cher date RIGHT HERE.

On a less silly note: did you know that Rust can have functions inside functions? I solve the 'where is the date?'-problem with the embedded extract_date-fn.

Parsing Kujira numbers from copypasta

#Rust pop-quiz answer for parsing Kujira numbers.

May I present kujira_nums.rs in my crypto/parsers library.

Parsing copypasta'd Kujira numbers

The problem of @TeamKujira numbers.

Kujira numbers, when copypasta'd come out as a mess:

0.9362 is pasted as

0.

9362

Ugh.

Write a Rust program that parses a Kujira number to its correct representation.

Sample file.

Announcement: automated CSV parsing in Rust

 🦀🦀🦀cRUSTaceans!🦀🦀🦀 

I've added a new fn to my csv_utils:

parse_csv<T>(skip: usize, f: Fn, lines: Lines)

• skips <skip> lines (header
• parses CSV with <f>
• returns Vec<T> objects from CSV <lines>

This goes a long way towards automating CSV parsing for me.

Some names are just wrong. Find and fix them.
