Rust documentation is here.
Read a vcf file, update the vCard object, and write back to file.
```rust use std::fs::{readtostring, write}; use vcardparser::parsevcards; use vcardparser::traits::HasValue; use vcardparser::vcard::value::Value; use vcardparser::vcard::value::valuetext::ValueTextData;
fn main () { let input = readtostring("contacts.vcf").unwrapor(String::from("BEGIN:VCARD\nVERSION:4.0\nFN:\nEND:VCARD\n")); let mut vcards = parsevcards(input.as_str()).expect("Unable to parse string.");
let vcard = vcards.first_mut().unwrap();
let mut property = vcard.get_property_by_name("FN").unwrap();
property.set_value(Value::from(ValueTextData::from("John Doe"))).unwrap();
vcard.set_property(&property).expect("Unable to update property.");
let mut data = String::new();
for vcard in vcards {
data.push_str(vcard.export().as_str())
}
write("contacts.vcf", data).expect("Unable to write file.");
} ```
