Enum git_ref::Target

pub enum Target {
    Peeled(ObjectId),
    Symbolic(FullName),
}

Denotes a ref target, equivalent to Kind, but with mutable data.

Variants

Peeled(ObjectId)

A ref that points to an object id

Symbolic(FullName)

A ref that points to another reference by its validated name, adding a level of indirection.

Note that this is an extension of gitoxide which will be helpful in logging all reference changes.

Implementations

impl Target

pub fn kind(&self) -> Kind

Returns the kind of the target the ref is pointing to.

pub fn is_null(&self) -> bool

Return true if this is a peeled target with a null hash

pub fn to_ref(&self) -> TargetRef<'_>

Interpret this owned Target as shared Target

pub fn try_id(&self) -> Option<&oid>

Interpret this target as object id which maybe None if it is symbolic.

pub fn id(&self) -> &oid

Interpret this target as object id or panic if it is symbolic.

pub fn into_id(self) -> ObjectId

Return the contained object id or panic

pub fn try_into_id(self) -> Result<ObjectId, Self>

Return the contained object id if the target is peeled or itself if it is not.

pub fn try_name(&self) -> Option<&FullNameRef>

Interpret this target as name of the reference it points to which maybe None if it an object id.

impl Ord for Target

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

This method returns an Ordering between self and other.

impl PartialEq<Target> for Target

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

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

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