[−][src]Struct parquet::file::reader::SerializedFileReader
A serialized implementation for Parquet FileReader.
Methods
impl<R: ParquetReader> SerializedFileReader<R>[src]
impl<R: ParquetReader> SerializedFileReader<R>pub fn new(reader: R) -> Result<Self>[src]
pub fn new(reader: R) -> Result<Self>Creates file reader from a Parquet file. Returns error if Parquet file does not exist or is corrupt.
Trait Implementations

impl<R: 'static + ParquetReader> FileReader for SerializedFileReader<R>fn metadata(&self) -> ParquetMetaDataPtr[src]
fn metadata(&self) -> ParquetMetaDataPtrGet metadata information about this file.
fn num_row_groups(&self) -> usize[src]
fn num_row_groups(&self) -> usizeGet the total number of row groups for this file.
fn get_row_group(&self, i: usize) -> Result<Box<dyn RowGroupReader>>[src]
fn get_row_group(&self, i: usize) -> Result<Box<dyn RowGroupReader>>Get the ith row group reader. Note this doesn't do bound check.
fn get_row_iter(&self, projection: Option<SchemaType>) -> Result<RowIter>[src]
fn get_row_iter(&self, projection: Option<SchemaType>) -> Result<RowIter>Get full iterator of Rows from a file (over all row groups). Read more

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?
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
