pub struct Record { /* private fields */ }

Expand description

Type definition of a generic record. A .dbf file is composed of many records

Implementations

source

impl Record

source

pub fn insert(
 &mut self,
 field_name: String,
 value: FieldValue
) -> Option<FieldValue>

Inserts a new value in the record, returning the old one if there was any

Example

let mut record = dbase::Record::default();
record.insert("FirstName".to_owned(), dbase::FieldValue::Character(Some("Yoshi".to_owned())));

source

pub fn get(&self, field_name: &str) -> Option<&FieldValue>

Returns the FieldValue for the given field name

source

pub fn get_mut(&mut self, field_name: &str) -> Option<&mut FieldValue>

Returns the mutable FieldValue for the given field name

source

pub fn remove(&mut self, field_name: &str) -> Option<FieldValue>

Removes the FieldValue for the given field name
