Struct char_device::CharDevice
source · [−]#[repr(transparent)]pub struct CharDevice(_);
Expand description
An unbuffered character device.
This is a wrapper around std::fs::File
which is intended for use with
character device “files” such as “/dev/tty”.
Implementations
Construct a new CharDevice
. Fail if the given handle isn’t a valid
handle for a character device, or it can’t be determined.
Construct a new CharDevice
from the given filename. Fail if the given
handle isn’t a valid handle for a character device, or it can’t be
determined.
Construct a new CharDevice
which discards writes and reads nothing.
This is “/dev/null” on Posix-ish platforms and “nul” on Windows.
Creates a new independently owned handle to the underlying device.
Return the number of bytes which are ready to be read immediately.
Trait Implementations

Extracts the raw handle, without taking any ownership.
Like AsRawHandle::as_raw_handle
and AsRawSocket::as_raw_socket
but can return either type. Read more
Consumes this object, returning the underlying handle. Read more
Like IntoHandle::into_handle
and
IntoSocket::into_socket
but can return either type. Read more

Like IntoRawHandle::into_raw_handle
and
IntoRawSocket::into_raw_socket
but can return either type. Read more
Pull some bytes from this source into the specified buffer, returning how many bytes were read. Read more
Like read
, except that it reads into a slice of buffers. Read more
can_vector
)Determines if this Read
er has an efficient read_vectored
implementation. Read more

. Read more
Read all bytes until EOF in this source, appending them to buf
. Read more

. Read more
read_buf
)Pull some bytes from this source into the specified buffer. Read more
read_buf

Creates a “by reference” adaptor for this instance of Read
. Read more
Creates an adapter which will chain this stream with another. Read more
Write a buffer into this writer, returning how many bytes were written. Read more
Flush this output stream, ensuring that all intermediately buffered contents reach their destination. Read more
can_vector
)Determines if this Write
r has an efficient write_vectored
implementation. Read more
Attempts to write an entire buffer into this writer. Read more
write_all_vectored
)Attempts to write multiple buffers into this writer. Read more
Writes a formatted string into this writer, returning any error encountered. Read more
