pub struct ReadFixed { /* private fields */ }
Expand description
Read from pre-mapped buffers.
The return values match those documented in the preadv2 (2)
man pages.
Implementations§
Source§impl ReadFixed
impl ReadFixed
Sourcepub const fn new(fd: Target, buf: *mut u8, len: u32, buf_index: u16) -> Self
pub const fn new(fd: Target, buf: *mut u8, len: u32, buf_index: u16) -> Self
The buf_index
is an index into an array of fixed buffers,
and is only valid if fixed buffers were registered.
pub const fn ioprio(self, ioprio: u16) -> Self
pub const fn offset(self, offset: off_t) -> Self
Sourcepub const fn rw_flags(self, rw_flags: RwFlags) -> Self
pub const fn rw_flags(self, rw_flags: RwFlags) -> Self
specified for read operations, contains a bitwise OR of per-I/O flags,
as described in the preadv2 (2)
man page.
pub fn build(self) -> Entry
