Struct Deserializer

pub struct Deserializer<R, O: Options> { /* private fields */ }

A Deserializer that reads bytes from a buffer.

This struct should rarely be used. In most cases, prefer the deserialize_from function.

The ByteOrder that is chosen will impact the endianness that is used to read integers out of the reader.

let d = Deserializer::new(&mut some_reader, SizeLimit::new());
serde::Deserialize::deserialize(&mut deserializer);
let bytes_read = d.bytes_read();
