Expand description

Logical types used by version 2.4.0+ of the Parquet format.

This is an entirely new struct as of version 4.0.0. The struct previously named LogicalType was renamed to ConvertedType. Please see the README.md for more details.

impl PartialEq for LogicalType

source§

fn eq(&self, other: &LogicalType) -> bool

1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
