#RawFd
pub struct RawFd {
fd : Int
// private fields
}A wrapper around a raw file descriptor that can be used to
perform asynchronous IO on the raw file descriptor.
This is useful for binding special file descriptors
that are not natively supported by moonbitlang/async.
#RawFd::RawFd
Create a new RawFd object from the underlying file descriptor.
The ownership of the file descriptor will be transferred to this function,
so the file descriptor must not be used or closed directly later,
even if creation of RawFd object failed.
#RawFd::read
Perform a single read/ReadFile system call
asynchronously on a raw file descriptor object.
Data will be read into buf[offset:offset+max_len].
The number of bytes actually read will be returned,
note that the number may be smaller than max_len.
A zero return value indicates EOF.
#RawFd::write
Perform a single write/WriteFile system call
asynchronously on a raw file descriptor object.
Data to write come from buf[offset:offset+len].
The number of bytes actually written will be returned,
note that the number may be smaller than len.
#RawFdStream
pub struct RawFdStream {
fd : Int
// private fields
}A wrapper around a raw file descriptor that can be used to
perform asynchronous stream-based IO on the raw file descriptor
via the @io.Reader/@io.Writer interface.
This is useful for binding special file descriptors
that are not natively supported by moonbitlang/async.
impl Reader for RawFdStream
async fn _direct_read(self : RawFdStream, buf : FixedArray[Byte], offset~ : Int, max_len~ : Int) -> Intimpl Writer for RawFdStream#RawFdStream::RawFdStream
Create a new RawFdStream object from the underlying file descriptor.
The ownership of the file descriptor will be transferred to this function,
so the file descriptor must not be used or closed directly later,
even if creation of RawFdStream object failed.
