this project is a tool CLI that can take CSV file and push its content into a sqlite database.

the CSV files have the following columns:

- Date
- Eau
- Scénic
- Zoé

the sqlite databases has been created with the following command:

CREATE TABLE "eau"
(
date    TEXT not null
primary key
unique,
releve  REAL not null,
comment TEXT
)

CREATE TABLE "voiture1" (
"date"	TEXT NOT NULL UNIQUE,
"releve"	INTEGER NOT NULL,
"comment"	TEXT,
PRIMARY KEY("date")
)

CREATE TABLE "voiture2"
(
date    TEXT    not null,
releve  INTEGER not null,
comment TEXT
)

CSV columns "Date" and "Eau" has to be pushed to database table "eau" on columns "date" and "releve". no push if "Eau" is empty
CSV columns "Date" and "Scénic" has to be pushed to database table "voiture1" on columns "date" and "releve". no push if "Scénic" is empty
CSV columns "Date" and "Zoé" has to be pushed to database table "voiture2" on columns "date" and "releve". no push if "Zoé" is empty

the CLI takes 2 parameters:

- first is the name of the CSV file
- second is the JDBC URL (for example, "jdbc:sqlite:/Users/kriss/NextCloud/Kriss/Dev/Perso/conso/db/conso.db")

when launched, the tool checks that:

- CSV file exists on the disk
- CSV file contains exactly the described columns
- Sqlite database is accessible through the JDBC URL
- Ensure there won't be any duplicates inserted in the database (which means if the tool is launched twice in a row, no new lines will be inserted)
- Tell the user how many new lines are going to be inserted in the database, and ask his agreement before proceeding
- Performs the insert in the database

this project is written in Rust.
