Struct libesedb::Record

pub struct Record<'a> { /* private fields */ }

Instance of a ESE database record in a currently open crate::Table.

Implementations

impl Record<'_>

pub fn value(&self, entry: i32) -> Result<Value>

Load a specific column/field value by entry number. Returned Value is bound to the lifetime of the database record.

pub fn count_values(&self) -> Result<i32>

Returns number of values (columns/fields) in the record.

pub fn iter_values(&self) -> Result<impl Iterator<Item = Result<Value>> + '_>

Create an iterator over all the (column/field) values in the table record. The [IterEntries] iterator and the returned Values are bound to the lifetime of the database record.

for value in record.iter_values()? {
    println!("{:?}", value?);
}
