Struct breez_sdk_core::lightning::io::StdoutLock
1.0.0 · source · pub struct StdoutLock<'a> { /* private fields */ }
Expand description
A locked reference to the Stdout
handle.
This handle implements the Write
trait, and is constructed via
the Stdout::lock
method. See its documentation for more.
§Note: Windows Portability Considerations
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.
In a process with a detached console, such as one using
#![windows_subsystem = "windows"]
, or in a child process spawned from such a process,
the contained handle will be null. In such cases, the standard library’s Read
and
Write
will do nothing and silently succeed. All other I/O operations, via the
standard library or via raw Windows API calls, will fail.
