Enum Reference 

pub enum Reference {
    Tag(String),
    Digest(Digest),
}

A parsed manifest reference: either a tag or a digest.

Variants

Tag(String)

Human-readable tag (e.g. latest, v1.2.3).

Digest(Digest)

Content-addressed digest.

Implementations

impl Reference

pub const fn is_tag(&self) -> bool

True when this reference is a tag.

pub const fn is_digest(&self) -> bool

True when this reference is a digest.

pub const fn as_digest(&self) -> Option<&Digest>

Borrow the digest, if this reference is one.

pub fn as_tag(&self) -> Option<&str>

Borrow the tag string, if this reference is one.

Trait Implementations

impl Clone for Reference

fn clone(&self) -> Reference

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Reference

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

Formats the value using the given formatter.

impl Display for Reference

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

Formats the value using the given formatter.

impl FromStr for Reference

type Err = OciError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Reference

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 PartialEq for Reference

fn eq(&self, other: &Reference) -> 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.
