[−][src]Enum parquet::column::page::Page
Parquet Page definition.
List of supported pages.
These are 1-to-1 mapped from the equivalent Thrift definitions, except buf which
used to store uncompressed bytes of the page.

Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S is the encoder/decoder state type, T is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
