Struct parquet2::metadata::Descriptor

pub struct Descriptor {
    pub primitive_type: PrimitiveType,
    pub max_def_level: i16,
    pub max_rep_level: i16,
}

A descriptor of a parquet column. It contains the necessary information to deserialize a parquet column.

Fields

primitive_type: PrimitiveType

The PrimitiveType of this column

max_def_level: i16

The maximum definition level

max_rep_level: i16

The maximum repetition level

Trait Implementations

impl Clone for Descriptor

fn clone(&self) -> Descriptor

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Descriptor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Descriptor

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Descriptor> for Descriptor

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

This method tests for self and other values to be equal, and is used by ==.

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

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