Struct OpenOptions

pub struct OpenOptions<Access: AccessMode> {
    pub create: Option<Create>,
    pub mode: Option<u16>,
    pub append: Option<bool>,
    pub force_sync: Option<bool>,
    pub update_access_time: Option<bool>,
    pub follow_links: Option<bool>,
    pub extra_flags: Option<i32>,
    /* private fields */
}

Available on Linux only.

A builder struct to help with opening files, using customizable options and logical defaults. Available via File::options to avoid additional use statements.
