Struct parquet::arrow::FieldLevels

source ·

pub struct FieldLevels { /* private fields */ }

Expand description

Schema information necessary to decode a parquet file as arrow Fields

In particular this stores the dremel-level information necessary to correctly interpret the encoded definition and repetition levels

Note: this is an opaque container intended to be used with lower-level APIs within this crate
