[−][src]Struct parquet::decoding::PlainDecoder
Plain decoding that supports all types.
Values are encoded back to back. For native types, data is encoded as little endian.
Floating point types are encoded in IEEE.
See PlainDecoder for more information.

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
