[−][src]Struct sval_json::Writer
A stream for writing structured data as json.
The stream internally wraps a std::io::Write
.
Examples
Create an owned json stream:
use sval::stream::OwnedStream; use sval_json::Writer; let mut stream = OwnedStream::begin(Writer::new(Vec::<u8>::new()))?; stream.any(42)?; let json = stream.end()?.into_inner(); assert_eq!(Some("42"), str::from_utf8(&json).ok());
Methods
impl<W> Writer<W> where
W: Write,
[src]
W: Write,
pub fn new(out: W) -> Self
[src]
Create a new json stream.
pub fn into_inner(self) -> W
[src]
Get the inner writer back out of the stream.
There is no validation done to ensure the data written is valid.
