Trait parquet_format_safe::thrift::varint::VarIntReader
source · [−]pub trait VarIntReader {
fn read_varint<VI: VarInt>(&mut self) -> Result<VI>;
}Expand description
A trait for reading VarInts from any other Reader.
It’s recommended to use a buffered reader, as many small reads will happen.
Required Methods
fn read_varint<VI: VarInt>(&mut self) -> Result<VI>
fn read_varint<VI: VarInt>(&mut self) -> Result<VI>
Returns either the decoded integer, or an error.
In general, this always reads a whole varint. If the encoded varint’s value is bigger
than the valid value range of VI, then the value is truncated.
On EOF, an io::Error with io::ErrorKind::UnexpectedEof is returned.
