Native Writer providers borrowing process standard output and standard error.

When to use

Construct StdoutWriter or StderrWriter at a native application edge and provide it for silk.writer.Writer. Portable code can supply its own Writer provider instead.

Details

Construction makes no foreign call. Writes complete each byte sequence through selected libc descriptor calls. Flush is a no-op because these providers have no userspace buffer.

Gotchas

A failed write may have committed a prefix. Descriptors remain process-owned and are never closed by these providers. The module is empty on WebAssembly and no-libc profiles.

Import as StdoutWriter with import silk.os_writer { StdoutWriter }.

Public declarations: 2.
