strsim | Calculate string similarity library , integrate multiple | Learning library

I want to know what is the best approach for a String Match with Python and a PSQL database. My db contains pubs names and zip codes. I want check if there are observations refering to the same pub but spelled differently by mistake.

Conceptually, I was thinking of looping through all the names and, for each other row in the same zip code, obtain a string similarity metric using strsim. If this metric is above a threshold, I insert it into another SQL table which stores the match candidates.

I think I am being inefficient. In "pseudo-code", having pub_table, candidates_table and using the JaroWinkler function, I mean to do something like:

I'm fairly new to Rust and decided to use it to port an existing project into it. I intended to use clap to handle CLI options, but I keep getting errors.

What do I need to do for clap to install correctly so that it's usable in my project as a dependency (e.g. extern crate clap; [...] use clap::App; [...]?

I haven't had problems with other crates (so far), so I'm not sure what's so different here or if there's a problem with the crate itself.

I've already seen a few questions (e.g. this one), which simply suggests that the dependency be added into the .toml file or don't seem to provide a solution to what I'm seeing.

I'm in Ubuntu Linux, if that makes a difference.

Adding clap = "2.33.0" to my Cargo.toml file (see https://crates.io/crates/clap) causes VSCode (through RLS) to log the following:

When I try to cargo build the 'hello world' of amethyst on Ubuntu 18.04, I get an error about missing libraries from lxbcb. I'm not sure what this error is trying to tell me or how to fix it. It seems like I'm missing libraries -lxcb-render, -lxcb-shap, and -lxcb-xfixes, but I can't seem to find them.

I am dipping my toes into Rust and can't seem to figure out how to compare rows of two csv files. I suspect my difficulty arises from trying to tackle the problem in entirely the wrong way, and so I am throwing myself onto the mercies of stackoverflow.

I am writing a simple program that reads two csv files of known fields, and then compares the edit distance of each element of column j in csv1 to each element of column j in csv2 for all columns j in J. At the moment, my code only succeeds in comparing the first row of csv1 to all the rows of csv2.

My pattern is to:

1. read the csvs into a struct Reader using the csv and serde crates (all good).
2. Create a struct Compare that holds two rows of type Reader, one from each csv.
3. Write a method for Compare that returns the string distances.

I have the core snippets of code below, and the whole thing can be accessed in the rust playground here.

The struct Record will hold a row,

I use a YAML file to define my command line interface. I parse the file using Clap's load_yaml! macro, which worked out fine for some time:
