Trait system_interface::fs::GetSetFdFlags

pub trait GetSetFdFlags {
    fn get_fd_flags(&self) -> Result<FdFlags>
    where
        Self: AsFilelike;
    fn new_set_fd_flags(&self, flags: FdFlags) -> Result<SetFdFlags<Self>>
    where
        Self: AsFilelike + FromFilelike + Sized;
    fn set_fd_flags(&mut self, set_fd_flags: SetFdFlags<Self>) -> Result<()>
    where
        Self: AsFilelike + Sized;
}

Extension trait that can indicate various I/O flags.

Required methods

fn get_fd_flags(&self) -> Result<FdFlags> where
    Self: AsFilelike, 

Query the “status” flags for the self file descriptor.

fn new_set_fd_flags(&self, flags: FdFlags) -> Result<SetFdFlags<Self>> where
    Self: AsFilelike + FromFilelike + Sized, 

Create a new SetFdFlags value for use with set_fd_flags.

Some platforms lack the ability to dynamically set the flags and implement set_fd_flags by closing and re-opening the resource and splitting it into two steps like this simplifies the lifetimes.

fn set_fd_flags(&mut self, set_fd_flags: SetFdFlags<Self>) -> Result<()> where
    Self: AsFilelike + Sized, 

Set the “status” flags for the self file descriptor.

This requires a SetFdFlags obtained from new_set_fd_flags.
