Function snarkvm_utilities::io::stderr_locked [−][src]
pub fn stderr_locked() -> StderrLock<'static>ⓘNotable traits for StderrLock<'_>
impl<'_> Write for StderrLock<'_>
🔬 This is a nightly-only experimental API. (
stdio_locked
)Expand description
Constructs a new locked handle to the standard error of the current process.
This handle is not buffered.
Note: Windows Portability Consideration
When operating in a console, the Windows implementation of this stream does not support non-UTF-8 byte sequences. Attempting to write bytes that are not valid UTF-8 will return an error.
Example
#![feature(stdio_locked)] use std::io::{self, Write}; fn main() -> io::Result<()> { let mut handle = io::stderr_locked(); handle.write_all(b"hello world")?; Ok(()) }
