Enum gix_odb::find::Header

pub enum Header {
    Loose {
        kind: Kind,
        size: u64,
    },
    Packed(Outcome),
}

An object header informing about object properties, without it being fully decoded in the process.

Variants

Loose

Fields

kind: Kind

The kind of the object.

size: u64

The size of the object’s data in bytes.

The object was not packed, but is currently located in the loose object portion of the database.

As packs are searched first, this means that in this very moment, the object whose header we retrieved is unique in the object database.

Packed(Outcome)

The object was present in a pack.

Note that this does not imply it is unique in the database, as it might be present in more than one pack and even as loose object.

Implementations

impl Header

pub fn kind(&self) -> Kind

Return the object kind of the object we represent.

pub fn size(&self) -> u64

Return the size of the object in bytes.

pub fn num_deltas(&self) -> Option<u32>

Return the amount of deltas decoded to obtain this header, if the object was packed.

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl From<(usize, Kind)> for Header

fn from((object_size, kind): (usize, Kind)) -> Self

Converts to this type from the input type.

impl From<Outcome> for Header

fn from(packed_header: Outcome) -> Self

Converts to this type from the input type.

impl Hash for Header

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 Header

fn cmp(&self, other: &Header) -> 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<Header> for Header

fn eq(&self, other: &Header) -> 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<Header> for Header

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