Struct Cached 

pub struct Cached;

A file opened for cached I/O: the system cache holds its writes, and its write-back can fail without telling the writer, so it claims WarrantyClass::BestEffort and needs no alignment.

Trait Implementations

impl Buffering for Cached

const FLAGS: u32 = 0

The CreateFileW flags this mode opens with.

const WARRANTY: WarrantyClass = WarrantyClass::BestEffort

The warranty class a file in this mode can claim.

const CAPABILITIES: Capabilities = Capabilities::NONE

What a file in this mode offers beyond the contract’s obligations.

const LOCAL_DEVICE_ONLY: bool = false

Whether the claim in WARRANTY holds only on a device of this machine, so that a file on a remote one is refused rather than given a class it cannot keep.

fn geometry() -> Geometry

The alignment a file in this mode starts with.

fn sector_geometry(sector_size: u32) -> Result<Geometry, GeometryError>

The alignment a raw volume or disk in this mode needs, addressed in sectors of sector_size bytes. Its transfers are whole sectors in either mode, so offsets and lengths are aligned to one; its buffers only when it is unbuffered, as the cache is what lets a cached transfer start anywhere.

impl Clone for Cached

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Cached

impl Debug for Cached

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
