pub struct PageMetaData {
    pub column_start: u64,
    pub num_values: i64,
    pub compression: Compression,
    pub descriptor: Descriptor,
}

This meta is a small part of ColumnChunkMetaData.

Fields

column_start: u64

The start offset of this column chunk in file.

num_values: i64

The number of values in this column chunk.

compression: Compression

Compression type

descriptor: Descriptor

The descriptor of this parquet column

Implementations

impl PageMetaData

pub fn new( column_start: u64, num_values: i64, compression: Compression, descriptor: Descriptor ) -> Self

Returns a new PageMetaData.

Trait Implementations

impl Clone for PageMetaData

fn clone(&self) -> PageMetaData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PageMetaData

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

Formats the value using the given formatter.

impl From<&ColumnChunkMetaData> for PageMetaData

fn from(column: &ColumnChunkMetaData) -> Self

Converts to this type from the input type.

impl PartialEq for PageMetaData

fn eq(&self, other: &PageMetaData) -> 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.
