deserialize

deserialize(stream)

Read a value written by serialize.

Examples

1. Deserialize a single value from a stream:

   julia> io = IOBuffer();
   julia> serialize(io, 42);
   julia> seekstart(io);
   julia> deserialize(io)
   42

   This example demonstrates deserializing a single value (42) from the IOBuffer stream.

2. Deserialize an array from a file:

   julia> file = open("data.bin", "r");
   julia> arr = deserialize(file);
   julia> close(file);

   In this example, the deserialize function is used to read and deserialize an array from a binary file named "data.bin".

3. Deserialize a complex object:

   julia> io = IOBuffer();
   julia> serialize(io, Dict("name" => "Julia", "version" => v"1.7.0"));
   julia> seekstart(io);
   julia> obj = deserialize(io)
   Dict{String,VersionNumber} with 2 entries:
    "version" => v"1.7.0"
    "name"    => "Julia"

   This example shows deserializing a complex object (a dictionary in this case) from the IOBuffer stream.

Common mistake example:

julia> data = "42";
julia> deserialize(data)
ERROR: MethodError: no method matching deserialize(::String)

In this example, the deserialize function is being used on a string ("42") instead of a stream object. It's important to pass a valid stream object to the deserialize function for successful deserialization.
