Enum TargetRef

pub enum TargetRef<'a> {
    Object(&'a oid),
    Symbolic(&'a FullNameRef),
}

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

Variants

Object(&'a oid)

A ref that points directly to an object id.

Symbolic(&'a FullNameRef)

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

Implementations

impl TargetRef<'_>

pub fn kind(&self) -> Kind

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

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

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

pub fn into_owned(self) -> Target

Convert this instance into an owned version, without consuming it.

Trait Implementations

impl<'a> Clone for TargetRef<'a>

fn clone(&self) -> TargetRef<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TargetRef<'a>

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

Formats the value using the given formatter.

impl<'a> From<TargetRef<'a>> for Target

fn from(src: TargetRef<'a>) -> Self

Converts to this type from the input type.

impl<'a> Hash for TargetRef<'a>

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<'a> Ord for TargetRef<'a>

fn cmp(&self, other: &TargetRef<'a>) -> 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<'a> PartialEq<TargetRef<'a>> for Target

fn eq(&self, other: &TargetRef<'a>) -> 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<'a> PartialEq for TargetRef<'a>

fn eq(&self, other: &TargetRef<'a>) -> 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<'a> PartialOrd for TargetRef<'a>

fn partial_cmp(&self, other: &TargetRef<'a>) -> 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.
