Struct minicbor_io::Writer

pub struct Writer<W> { /* private fields */ }

Wraps a std::io::Write and writes length-delimited CBOR values.

Implementations

impl<W> Writer<W>

pub fn new(writer: W) -> Self

Create a new writer with a max. buffer size of 512KiB.

pub fn with_buffer(writer: W, buffer: Vec<u8>) -> Self

Create a new writer with a max. buffer size of 512KiB.

pub fn set_max_len(&mut self, val: u32)

Set the max. buffer size in bytes.

If length values greater than this are encoded, an Error::InvalidLen will be returned.

pub fn writer(&self) -> &W

Get a reference to the inner writer.

pub fn writer_mut(&mut self) -> &mut W

Get a mutable reference to the inner writer.

pub fn into_parts(self) -> (W, Vec<u8>)

Deconstruct this writer into the inner writer and the buffer.

impl<W: Write> Writer<W>

pub fn write<T: Encode<()>>(&mut self, val: T) -> Result<usize, Error>

Encode and write a CBOR value and return its size in bytes.

pub fn write_with<C, T: Encode<C>>( &mut self, val: T, ctx: &mut C ) -> Result<usize, Error>

Like Writer::write but accepting a user provided encoding context.

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

Flush the inner Writer.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
