Struct SseField 

pub struct SseField<W: Write>(/* private fields */);

A field in an SSE message.

Each field has a name and a value. The assigned name is automatically written when the object is initialized, and the value is then appended by writing into the SseField object any number of times. When the SseField object goes out of scope, the field is terminated.

The written value must not contain any \n newline characters.

Trait Implementations

impl<W: Write> Drop for SseField<W>

Writes the field terminating sequence on drop.

fn drop(&mut self)

Executes the destructor for this type.

impl<W: Write> Write for SseField<W>

Appends to the value of the current field.

fn write(&mut self, buf: &[u8]) -> Result<usize>

Writes a buffer into this writer, returning how many bytes were written.

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

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
