sourcepub fn new(fd: SafeDescriptor) -> Result<Descriptor>
pub fn new(fd: SafeDescriptor) -> Result<Descriptor>
Creates a new AsyncDescriptor in a nonblocking state.
sourcepub async fn wait_readable(&self) -> Result<()>
pub async fn wait_readable(&self) -> Result<()>
Waits for self to become readable. This function is edge-triggered rather than
level-triggered so callers should make sure that the underlying descriptor has been fully
drained before calling this method.
sourcepub async fn wait_writable(&self) -> Result<()>
pub async fn wait_writable(&self) -> Result<()>
Waits for self to become writable. This function is edge-triggered rather than
level-triggered so callers should make sure that the underlying descriptor is actually full
before calling this method.
