pub struct ManifestStore { /* private fields */ }

Available on crate feature v1_api only.

A Container for a set of Manifests and a ValidationStatus list

Implementations

impl ManifestStore

pub fn new() -> Self

allocates a new empty ManifestStore

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

Returns a reference to the active manifest label or None

pub fn get_active(&self) -> Option<&Manifest>

Returns a reference to the active manifest or None

pub fn manifests(&self) -> &HashMap<String, Manifest>

Returns a reference to manifest HashMap

pub fn get(&self, label: &str) -> Option<&Manifest>

Returns a reference to the requested manifest or None

pub fn get_resource( &self, uri: &str, stream: impl Write + Read + Seek + Send ) -> Result<u64>

pub fn validation_status(&self) -> Option<&[ValidationStatus]>

Returns a reference the ValidationStatus Vec or None

pub fn from_manifest(manifest: &Manifest) -> Result<Self>

Creates a new Manifest Store from a Manifest

pub fn from_bytes( format: &str, image_bytes: &[u8], verify: bool ) -> Result<ManifestStore>

Generate a Store from a format string and bytes.

pub fn from_stream( format: &str, stream: impl Read + Seek + Send, verify: bool ) -> Result<ManifestStore>

Generate a Store from a format string and stream.

pub async fn from_stream_async( format: &str, stream: impl Read + Seek + Send, verify: bool ) -> Result<ManifestStore>

Generate a Store from a format string and stream.

pub fn from_file<P: AsRef<Path>>(path: P) -> Result<ManifestStore>

Available on crate feature file_io only.

Loads a ManifestStore from a file Example:

use c2pa::ManifestStore;
let manifest_store = ManifestStore::from_file("tests/fixtures/C.jpg")?;
println!("{}", manifest_store);

pub fn from_file_with_resources<P: AsRef<Path>>( path: P, resource_path: P ) -> Result<ManifestStore>

Available on crate feature file_io only.

Loads a ManifestStore from a file adding resources to a folder Example:

use c2pa::ManifestStore;
let manifest_store = ManifestStore::from_file_with_resources(
    "tests/fixtures/C.jpg",
    "../target/tmp/manifest_store",
)?;
println!("{}", manifest_store);

pub async fn from_bytes_async( format: &str, image_bytes: &[u8], verify: bool ) -> Result<ManifestStore>

Loads a ManifestStore from a file

pub async fn from_fragment_bytes_async( format: &str, init_bytes: &[u8], fragment_bytes: &[u8], verify: bool ) -> Result<ManifestStore>

Loads a ManifestStore from an init segment and fragment. This would be used to load and validate fragmented MP4 files that span multiple separate assets.

pub async fn from_manifest_and_asset_bytes_async( manifest_bytes: &[u8], format: &str, asset_bytes: &[u8] ) -> Result<ManifestStore>

Asynchronously loads a manifest from a buffer holding a binary manifest (.c2pa) and validates against an asset buffer

Example: Creating a manifest store from a .c2pa manifest and validating it against an asset

use c2pa::{Result, ManifestStore};

        let asset_bytes = include_bytes!("../tests/fixtures/cloud.jpg");
        let manifest_bytes = include_bytes!("../tests/fixtures/cloud_manifest.c2pa");

        let manifest_store = ManifestStore::from_manifest_and_asset_bytes_async(manifest_bytes, "image/jpg", asset_bytes)
            .await
            .unwrap();

        println!("{}", manifest_store);
}

pub fn from_manifest_and_asset_bytes( manifest_bytes: &[u8], format: &str, asset_bytes: &[u8] ) -> Result<ManifestStore>

Synchronously loads a manifest from a buffer holding a binary manifest (.c2pa) and validates against an asset buffer

Example: Creating a manifest store from a .c2pa manifest and validating it against an asset

use c2pa::{Result, ManifestStore};

        let asset_bytes = include_bytes!("../tests/fixtures/cloud.jpg");
        let manifest_bytes = include_bytes!("../tests/fixtures/cloud_manifest.c2pa");

        let manifest_store = ManifestStore::from_manifest_and_asset_bytes(manifest_bytes, "image/jpg", asset_bytes)
            .unwrap();

        println!("{}", manifest_store);
}
