Struct bincode::internal::Deserializer
[−]
[src]
pub struct Deserializer<R, S: SizeLimit, E: ByteOrder> { /* fields omitted */ }
A Deserializer that reads bytes from a buffer.
This struct should rarely be used.
In most cases, prefer the decode_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();
