Struct ArtifactManifest

pub struct ArtifactManifest { /* private fields */ }

The OCI Artifact manifest describes content addressable artifacts in order to store them along side container images in a registry.

Implementations

impl ArtifactManifest

pub fn media_type(&self) -> &MediaType

This property MUST be used and contain the media type application/vnd.oci.artifact.manifest.v1+json.

pub fn artifact_type(&self) -> &MediaType

This property SHOULD be used and contain the mediaType of the referenced artifact. If defined, the value MUST comply with RFC 6838, including the naming requirements in its section 4.2, and MAY be registered with IANA.

pub fn blobs(&self) -> &Vec<Descriptor>

This OPTIONAL property is an array of objects and each item in the array MUST be a descriptor. Each descriptor represents an artifact of any IANA mediaType. The list MAY be ordered for certain artifact types like scan results.

pub fn subject(&self) -> &Option<Descriptor>

This OPTIONAL property specifies a descriptor of another manifest. This value, used by the referrers API, indicates a relationship to the specified manifest.

pub fn annotations(&self) -> &Option<HashMap<String, String>>

This OPTIONAL property contains additional metadata for the artifact manifest. This OPTIONAL property MUST use the annotation rules. See Pre-Defined Annotation Keys. Annotations MAY be used to filter the response from the referrers API.

impl ArtifactManifest

pub fn blobs_mut(&mut self) -> &mut Vec<Descriptor>

This OPTIONAL property is an array of objects and each item in the array MUST be a descriptor. Each descriptor represents an artifact of any IANA mediaType. The list MAY be ordered for certain artifact types like scan results.

pub fn annotations_mut(&mut self) -> &mut Option<HashMap<String, String>>

This OPTIONAL property contains additional metadata for the artifact manifest. This OPTIONAL property MUST use the annotation rules. See Pre-Defined Annotation Keys. Annotations MAY be used to filter the response from the referrers API.

impl ArtifactManifest

pub fn set_artifact_type(&mut self, val: MediaType) -> &mut Self

This property SHOULD be used and contain the mediaType of the referenced artifact. If defined, the value MUST comply with RFC 6838, including the naming requirements in its section 4.2, and MAY be registered with IANA.

pub fn set_blobs(&mut self, val: Vec<Descriptor>) -> &mut Self

This OPTIONAL property is an array of objects and each item in the array MUST be a descriptor. Each descriptor represents an artifact of any IANA mediaType. The list MAY be ordered for certain artifact types like scan results.

pub fn set_subject(&mut self, val: Option<Descriptor>) -> &mut Self

This OPTIONAL property specifies a descriptor of another manifest. This value, used by the referrers API, indicates a relationship to the specified manifest.

pub fn set_annotations( &mut self, val: Option<HashMap<String, String>>, ) -> &mut Self

This OPTIONAL property contains additional metadata for the artifact manifest. This OPTIONAL property MUST use the annotation rules. See Pre-Defined Annotation Keys. Annotations MAY be used to filter the response from the referrers API.

impl ArtifactManifest

pub fn from_file(path: impl AsRef<Path>) -> Result<Self>

Attempts to load an image manifest from a file.

Errors

• OciSpecError::Io if the file does not exist
• OciSpecError::SerDe if the image manifest cannot be deserialized.

Example

use oci_spec::image::ArtifactManifest;

let artifact_manifest = ArtifactManifest::from_file("manifest.json").unwrap();

pub fn from_reader<R: Read>(reader: R) -> Result<Self>

Attempts to load an image manifest from a stream.

Errors

• OciSpecError::SerDe if the manifest cannot be deserialized.

Example

use oci_spec::image::ArtifactManifest;
use std::fs::File;

let reader = File::open("manifest.json").unwrap();
let artifact_manifest = ArtifactManifest::from_reader(reader).unwrap();

pub fn to_file<P: AsRef<Path>>(&self, path: P) -> Result<()>

Attempts to write an image manifest to a file as JSON. If the file already exists, it will be overwritten.

Errors

• OciSpecError::SerDe if the image manifest cannot be serialized.

Example

use oci_spec::image::ArtifactManifest;

let artifact_manifest = ArtifactManifest::from_file("manifest.json").unwrap();
artifact_manifest.to_file("my-manifest.json").unwrap();

pub fn to_file_pretty<P: AsRef<Path>>(&self, path: P) -> Result<()>

Attempts to write an image manifest to a file as pretty printed JSON. If the file already exists, it will be overwritten.

Errors

• OciSpecError::SerDe if the image manifest cannot be serialized.

Example

use oci_spec::image::ArtifactManifest;

let artifact_manifest = ArtifactManifest::from_file("manifest.json").unwrap();
artifact_manifest.to_file_pretty("my-manifest.json").unwrap();

pub fn to_writer<W: Write>(&self, writer: &mut W) -> Result<()>

Attempts to write an image manifest to a stream as JSON.

Errors

• OciSpecError::SerDe if the image manifest cannot be serialized.

Example

use oci_spec::image::ArtifactManifest;

let artifact_manifest = ArtifactManifest::from_file("manifest.json").unwrap();
let mut writer = Vec::new();
artifact_manifest.to_writer(&mut writer);

pub fn to_writer_pretty<W: Write>(&self, writer: &mut W) -> Result<()>

Attempts to write an image manifest to a stream as pretty printed JSON.

Errors

• OciSpecError::SerDe if the image manifest cannot be serialized.

Example

use oci_spec::image::ArtifactManifest;

let artifact_manifest = ArtifactManifest::from_file("manifest.json").unwrap();
let mut writer = Vec::new();
artifact_manifest.to_writer_pretty(&mut writer);

pub fn to_string(&self) -> Result<String>

Attempts to write an image manifest to a string as JSON.

Errors

• OciSpecError::SerDe if the image configuration cannot be serialized.

Example

use oci_spec::image::ArtifactManifest;

let artifact_manifest = ArtifactManifest::from_file("manifest.json").unwrap();
let json_str = artifact_manifest.to_string().unwrap();

pub fn to_string_pretty(&self) -> Result<String>

Attempts to write an image manifest to a string as pretty printed JSON.

Errors

• OciSpecError::SerDe if the image configuration cannot be serialized.

Example

use oci_spec::image::ArtifactManifest;

let artifact_manifest = ArtifactManifest::from_file("manifest.json").unwrap();
let json_str = artifact_manifest.to_string_pretty().unwrap();
