Function dia_args::parse_stream[−][src]

pub fn parse_stream<R>(stream: &mut R, max_size: Option<u64>) -> Result<Args> where
    R: Read,

Parses a stream of strings, separated by null byte (`0`)

This function can be useful for securely passing/parsing arguments across processes.

Notes

If max_size is zero, an error is returned. If None, MAX_DIA_ARGS_FILE_SIZE will be used. If the stream has more data than provided value, an error is returned.
If the stream contains an invalid UTF-8 string, an error is returned.
The stream is used as-is. So you might want to use BufReader.

Examples

let stream = b"run\0--faster=true";

let args = dia_args::parse_stream(&mut &stream[..], None)?;
assert_eq!(args.cmd(), Some("run"));
assert_eq!(args.get(&["--faster"])?, Some(true));
