Variants

`Optional(DefLevelsDecoder<'a>, Casted<'a, T>)`

A page of optional values

`Required(Casted<'a, T>)`

A page of required values

`RequiredDictionary(Dictionary<'a, T>)`

A page of required, dictionary-encoded values

`OptionalDictionary(DefLevelsDecoder<'a>, Dictionary<'a, T>)`

A page of optional, dictionary-encoded values

Implementations

impl<'a, T: NativeType> NativePageState<'a, T>

pub fn try_new(page: &'a DataPage) -> Result<Self, Error>
