write
write(stream, x)
Write the canonical binary representation of a value to the given stream. Returns the number of bytes written into the stream.
You can write multiple values with the same :func:write call.
i.e. the following are equivalent:
write(stream, x, y...)
write(stream, x) + write(stream, y...)Examples
julia> io = IOBuffer(); # Create an in-memory buffer to write to
julia> write(io, 10)
8
julia> write(io, 3.14)
8
julia> write(io, "Hello, Julia!")
14
julia> String(take!(io))
"10\x00\x00\x00\x00\x00\x00\x00\x1f\x85\xebQ\xb8!\xc7Hello, Julia!"In this example, we create an in-memory buffer io using IOBuffer(). We then use the write function to write different values to the buffer. The function returns the number of bytes written into the stream. Finally, we convert the buffer content to a string using String(take!(io)).
Note that the write function can be used to write multiple values with the same call. The following two examples are equivalent:
julia> io = IOBuffer();
julia> write(io, 10, 3.14, "Hello, Julia!")
30
julia> String(take!(io))
"10\x00\x00\x00\x00\x00\x00\x00\x1f\x85\xebQ\xb8!\xc7Hello, Julia!"julia> io = IOBuffer();
julia> write(io, 10) + write(io, 3.14) + write(io, "Hello, Julia!")
30
julia> String(take!(io))
"10\x00\x00\x00\x00\x00\x00\x00\x1f\x85\xebQ\xb8!\xc7Hello, Julia!"See Also
