Struct std::process::ChildStdin

[+] Show type declaration

pub struct ChildStdin { /* fields omitted */ }

[−] Expand description

A handle to a child process's standard input (stdin).

This struct is used in the stdin field on Child.

When an instance of ChildStdin is dropped, the ChildStdin's underlying file handle will be closed. If the child process was blocked on input prior to being dropped, it will become unblocked after dropping.
