dbase-parser: A dbaseIII/IV/foxpro iterative parser for rust

This crate provides the ability to read and parse dbf files, yielding typed objects as it goes. It is efficient, versatile, well-tested and, above all, maintained.

The motivation behind this is documented here. In particular, no parsing crate supported the memo (M) type, let alone the two variants of it.

Build Status Coverage Status

A disclaimer on versioning

As the crate is still under active development, versions may change relatively fast. Until we're at 1.x, consider the public API to be unstable.

In particular, the FieldValue enum may gain additional types as different DBF file formats surface.

Installation

Add dbase_parser to your dependencies.

Usage

Opening a file and streaming rows is a simple set of operations, as shown below:

extern crate dbase_parser;
use dbase_parser::{FieldValue, open};

let dbase_file = open("data.dbf");
let amount:f64 = dbase_file
  .map(|db| {
    db.into_iter().fold(0.0, |current, record| {
      record.get("amount").map(|value| match value {
        FieldValue::Numeric(value) => value.clone(),
        _ => 0.0
      }).unwrap_or(0.0)

  })
}).unwrap_or(0.0);

More options and types are available under the hood and exposed through the documentation.

Bugs

If you've found a bug or issue, don't hesitate to file an issue. If you are parsing a file, don't forget to attach it to your issue; make sure to anonymize the data if needed.
