Struct ObjectSource

#[repr(C)]
pub struct ObjectSource {
    pub id: ObjID,
    pub src_start: u64,
    pub dest_start: u64,
    pub len: usize,
}

Specifications for an object-copy from a source object. The specified ranges are source:[src_start, src_start + len) copied to :[dest_start, dest_start + len). Each range must start within an object, and end within the object.

Fields

id: ObjID

The ID of the source object, or zero for filling destination with zero.

src_start: u64

The offset into the source object to start the copy. If id is zero, this field is reserved for future use.

dest_start: u64

The offset into the dest object to start the copy or zero.

len: usize

The length of the copy or zero.

Implementations

impl ObjectSource

pub fn new_copy(id: ObjID, src_start: u64, dest_start: u64, len: usize) -> Self

Construct a new ObjectSource.

pub fn new_zero(dest_start: u64, len: usize) -> Self

Construct a new ObjectSource.

Trait Implementations

impl Clone for ObjectSource

fn clone(&self) -> ObjectSource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectSource

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

Formats the value using the given formatter.

impl Default for ObjectSource

fn default() -> ObjectSource

Returns the “default value” for a type.

impl Ord for ObjectSource

fn cmp(&self, other: &ObjectSource) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ObjectSource

fn eq(&self, other: &ObjectSource) -> 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.

impl PartialOrd for ObjectSource

fn partial_cmp(&self, other: &ObjectSource) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
