Struct FdReader2 

pub struct FdReader2<S> { /* private fields */ }

Input function that reads from a file descriptor

An instance of FdReader2<S> contains a Rc<Concurrent<S>> to read input from a file descriptor.

Although FdReader2 implements Clone, it does not mean you can create and keep a copy of a FdReader2 instance to replay the input later. Since both the original and clone share the same Concurrent<S>, reading a line from one instance will affect the next read from the other.

FdReader2 is a variant of FdReader that depends on Concurrent<S> instead of SharedSystem.

Implementations

impl<S> FdReader2<S>

pub fn new(fd: Fd, system: Rc<Concurrent<S>>) -> Self

Creates a new FdReader2 instance.

The fd argument is the file descriptor to read from. It should be readable, have the close-on-exec flag set, and remain open for the lifetime of the FdReader2 instance.
