Struct NixWrite

pub struct NixWrite<W> {
    pub inner: W,
}

A wrapper around a std::io::Write, adding support for the nix wire format.

Fields

inner: W

Implementations

impl<W: Write> NixWrite<W>

pub fn write_u64(&mut self, n: u64) -> Result<()>

Write an integer to the wire.

pub fn write_string(&mut self, s: &[u8]) -> Result<()>

Write a “string” (really, a byte buffer) to the wire.

pub fn write_nix(&mut self, data: &impl Serialize) -> Result<()>

Write any serializable type to the wire.

Warning: don’t call this with [u8] data: that will (attempt to) serialize a sequence of u8s, and then panic because the nix wire protocol only supports 64-bit integers. If you want to write a byte buffer, use NixWrite::write_string instead.

pub fn flush(&mut self) -> Result<()>

Flush the underlying writer.
