Struct dockerfile_parser::ImageRef

pub struct ImageRef {
    pub registry: Option<String>,
    pub image: String,
    pub tag: Option<String>,
}

A parsed docker image reference

The Display impl may be used to convert a parsed image back to a plain string:

use dockerfile_parser::ImageRef;

let image = ImageRef::parse("alpine:3.11");
assert_eq!(image.registry, None);
assert_eq!(image.image, "alpine");
assert_eq!(image.tag, Some("3.11".to_string()));
assert_eq!(format!("{}", image), "alpine:3.11");

Fields

registry: Option<String>

an optional registry, generally Docker Hub if unset

image: String

an image string, possibly including a user or organization name

tag: Option<String>

An optional image tag (after the colon, e.g. :1.2.3), generally inferred to mean :latest if unset

Methods

impl ImageRef

pub fn parse(s: &str) -> ImageRef

Parses an ImageRef from a string.

This is not fallible, however malformed image strings may return unexpected results.

Trait Implementations

impl Clone for ImageRef

fn clone(&self) -> ImageRef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImageRef

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

Formats the value using the given formatter.

impl Display for ImageRef

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

Formats the value using the given formatter.

impl Eq for ImageRef

impl PartialEq<ImageRef> for ImageRef

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

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