pub struct DefaultOptions(/* private fields */);Expand description
The default options for bincode serialization/deserialization.
§Defaults
By default bincode will use little-endian encoding for multi-byte integers, and will not limit the number of serialized/deserialized bytes.
§Configuring DefaultOptions
DefaultOptions implements the Options trait, which means it exposes functions to change the behavior of bincode.
For example, if you wanted to limit the bincode deserializer to 1 kilobyte of user input:
use bincode::Options;
let my_options = bincode::DefaultOptions::new().with_limit(1024);§DefaultOptions struct vs. functions
The default configuration used by this struct is not the same as that used by the bincode helper functions in the root of this crate. See the config module for more details
