Struct WindowsCallbackRange 

pub struct WindowsCallbackRange { /* private fields */ }

Owned CFAPI callback range preserving the native CF_EOF distinction.

Implementations

impl WindowsCallbackRange

pub fn exact(offset: u64, length: u64) -> Result<Self>

Creates one exact non-empty range and rejects end overflow.

Errors

Returns an error when validation fails or an underlying backend, store, or platform operation fails.

pub fn to_end(offset: u64) -> Result<Self>

Creates a range extending from offset through the current end of file.

Errors

Returns an error when validation fails or an underlying backend, store, or platform operation fails.

pub fn from_cfapi(offset: i64, length: i64) -> Result<Self>

Converts the signed CFAPI offset/length pair into an owned range.

Errors

Returns an error when validation fails or an underlying backend, store, or platform operation fails.

pub const fn offset(self) -> u64

Returns the first requested byte offset.

pub const fn length(self) -> WindowsCallbackRangeLength

Returns the exact native length semantics.

pub const fn end_exclusive(self) -> Option<u64>

Returns the exclusive end for an exact range, or None for ToEnd.

Trait Implementations

impl Clone for WindowsCallbackRange

fn clone(&self) -> WindowsCallbackRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowsCallbackRange

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

Formats the value using the given formatter.

impl Hash for WindowsCallbackRange

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WindowsCallbackRange

fn eq(&self, other: &WindowsCallbackRange) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
