Enum Kind

pub enum Kind {
    Base(Kind),
    DeltaRef {
        object_index: usize,
    },
    DeltaOid {
        id: ObjectId,
    },
}

Available on crate feature generate only.

The kind of pack entry to be written

Variants

Base(Kind)

A complete base object, including its kind

DeltaRef

A delta against the object with the given index. It’s always an index that was already encountered to refer only to object we have written already.

Fields

object_index: usize

The absolute index to the object to serve as base. It’s up to the writer to maintain enough state to allow producing a packed delta object from it.

DeltaOid

A delta against the given object as identified by its ObjectId. This is the case for thin packs only, i.e. those that are sent over the wire. Note that there is the option of the ObjectId being used to refer to an object within the same pack, but it’s a discontinued practice which won’t be encountered here.

Fields

id: ObjectId

The object serving as base for this delta

Trait Implementations

impl Clone for Kind

fn clone(&self) -> Kind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Kind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Kind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Kind

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 Ord for Kind

fn cmp(&self, other: &Kind) -> 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 Kind

fn eq(&self, other: &Kind) -> 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 Kind

fn partial_cmp(&self, other: &Kind) -> 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.

impl Serialize for Kind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Kind

impl Eq for Kind

impl StructuralPartialEq for Kind
