Crate datasus_dbc
source ·Expand description
Decompress *.dbc
files usually found in Brazil’s DATASUS ftp server into *.dbf
files.
The underlying decompression algorithm used in *.dbc
files is the implode algorithm from the PKWARE Data Compression Library.
This library uses Aaron Griffith’s rust implementation of the implode algorithm. Also,
this library is heavily inspired by Daniela Petruzalek’s pysus. I want to thank both of them, without their work this library
would not be possible.
Examples
To decompress a *.dbc
file into a *.dbf
use decompress
:
datasus_dbc::decompress("input.dbc", "output.dbf");
If you want more control over how the *.dbc
file is read,
you can pass a File
or other type which implements Read
to into_dbf_reader
to get a reader of the decompressed content.
use std::io::Read;
let dbc_file = std::fs::File::open("input.dbc").unwrap();
let mut dbf_reader = datasus_dbc::into_dbf_reader(dbc_file).unwrap();
let mut buf: Vec<u8> = Default::default();
dbf_reader.read_to_end(&mut buf).unwrap();
println!("{:?}", &buf[0..20]);
Enums
Functions
- Decompress a .dbc file into a .dbf file
- Transform a .dbc reader into a .dbf reader. Make sure
dbc_reader
starts at the beginning of the file.
