Enum git_pack::index::traverse::Algorithm

pub enum Algorithm {
    DeltaTreeLookup,
    Lookup,
}

The way we verify the pack

Variants

DeltaTreeLookup

Build an index to allow decoding each delta and base exactly once, saving a lot of computational resource at the expense of resident memory, as we will use an additional DeltaTree to accelerate delta chain resolution.

Lookup

We lookup each object similarly to what would happen during normal repository use. Uses more compute resources as it will resolve delta chains from back to front, but start right away without indexing or investing any memory in indices.

This option may be well suited for big packs in memory-starved system that support memory mapping.

Trait Implementations

impl Clone for Algorithm

fn clone(&self) -> Algorithm

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Algorithm

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

Formats the value using the given formatter.

impl Default for Algorithm

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Algorithm

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Algorithm

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 Algorithm

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Algorithm> for Algorithm

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<Algorithm> for Algorithm

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Algorithm

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 Algorithm

impl Eq for Algorithm

impl StructuralEq for Algorithm
