Implementations

impl ImageProxy

pub async fn new() -> Result<Self>

Create an image proxy that fetches the target image, using default configuration.

pub async fn new_with_config(config: ImageProxyConfig) -> Result<Self>

Create an image proxy that fetches the target image

pub async fn open_image(&self, imgref: &str) -> Result<OpenedImage>

pub async fn close_image(&self, img: &OpenedImage) -> Result<()>

pub async fn fetch_manifest(
    &self,
    img: &OpenedImage
) -> Result<(String, Vec<u8>)>

Fetch the manifest. For more information on OCI manifests, see https://github.com/opencontainers/image-spec/blob/main/manifest.md

pub async fn get_blob(
    &self,
    img: &OpenedImage,
    digest: &str,
    size: u64
) -> Result<(impl AsyncBufRead + Send + Unpin, impl Future<Output = Result<()>> + Unpin + '_)>

Fetch a blob identified by e.g. sha256:<digest>. https://github.com/opencontainers/image-spec/blob/main/descriptor.md

The requested size and digest are verified (by the proxy process).

pub async fn finalize(self) -> Result<()>

Close the connection and wait for the child process to exit successfully.
