pub struct Row { /* fields omitted */ }
Expand description
Row
represents a nested Parquet record.
Implementations
impl Row
[src]
impl Row
[src]pub fn get_column_iter(&self) -> RowColumnIter<'_>
[src]
pub fn get_column_iter(&self) -> RowColumnIter<'_>
[src]Get an iterator to go through all columns in the row.
Example
use std::fs::File; use parquet::record::Row; use parquet::file::reader::{FileReader, SerializedFileReader}; let file = File::open("/path/to/file").unwrap(); let reader = SerializedFileReader::new(file).unwrap(); let row: Row = reader.get_row_iter(None).unwrap().next().unwrap(); for (idx, (name, field)) in row.get_column_iter().enumerate() { println!("column index: {}, column name: {}, column value: {}", idx, name, field); }
