Module csv 

Available on crate feature csv only.

Named peers from CSV text. Needs the csv feature.

Local trust has one from,to[,weight] record per line, pre-trust one peer[,weight] record. Peer names are arbitrary strings and weights default to 1.

use eigentrust::csv::Network;
use eigentrust::EigenTrustOptions;

let network = Network::from_csv(
    "from,to,weight\nalice,bob,2\nbob,carol,1\ncarol,alice,1\n",
    "alice\n",
)?;
let result = network.eigentrust(&EigenTrustOptions::default())?;
let ranking = network.ranking(&result);
assert_eq!(ranking[0].0, "alice");

The reader accepts standard CSV: quoted fields ("Smith, J"), escaped quotes, an optional header row, spaces around fields, CRLF line endings and a UTF-8 BOM. Blank lines are skipped and columns after the weight are ignored.

The first record is a header when its weight column is not a number, or, for records without a weight column, when every field is a common header name such as from, to, peer or weight. A weight that fails to parse on any later line is an error.
