Struct ParquetMetaDataOptions 

Source 
pub struct ParquetMetaDataOptions {
    schema_descr: Option<SchemaDescPtr>,
}
Expand description

Options that can be set to control what parts of the Parquet file footer metadata will be decoded and made present in the ParquetMetaData returned by ParquetMetaDataReader and ParquetMetaDataPushDecoder.

Fields§

§schema_descr: Option<SchemaDescPtr>

Implementations§

Source§

impl ParquetMetaDataOptions

Source

pub fn new() -> Self

Return a new default ParquetMetaDataOptions.

Source

pub fn schema(&self) -> Option<&SchemaDescPtr>

Returns an optional SchemaDescPtr to use when decoding. If this is not None then the schema in the footer will be skipped.

Source

pub fn set_schema(&mut self, val: SchemaDescPtr)

Provide a schema to use when decoding the metadata.

Source

pub fn with_schema(self, val: SchemaDescPtr) -> Self

Provide a schema to use when decoding the metadata. Returns Self for chaining.
