Crate delivery_blob 

Library for creating, serializing, and deserializing RFC 0207 delivery blobs. For example, to create a Type 1 delivery blob:

use delivery_blob::{CompressionMode, Type1Blob};
let merkle = "68d131bc271f9c192d4f6dcd8fe61bef90004856da19d0f2f514a7f4098b0737";
let data: Vec<u8> = vec![0xFF; 8192];
let payload: Vec<u8> = Type1Blob::generate(&data, CompressionMode::Attempt);

Modules

compression

Implementation of chunked-compression library in Rust. Archives can be created by making a new ChunkedArchive and serializing/writing it. An archive’s header can be verified and seek table decoded using decode_archive.

Structs

DeliveryBlobHeader

Typed header of an RFC 0207 compliant delivery blob.

Type1Blob

Header + metadata fields of a Type 1 blob.

Enums

CompressionMode

Mode specifying when a delivery blob should be compressed.

DecompressError

DeliveryBlobError

DeliveryBlobType

Type of delivery blob.

Functions

calculate_digest

Calculate the merkle root digest of the decompressed delivery_blob, delivery blob type is auto detected.

decompress

Decompress a delivery blob in delivery_blob, delivery blob type is auto detected.

decompress_to

Decompress a delivery blob in delivery_blob, and write the decompressed blob to writer, delivery blob type is auto detected.

decompressed_size

Returns the decompressed size of delivery_blob, delivery blob type is auto detected.

decompressed_size_from_reader

Returns the decompressed size of the delivery blob from reader.

generate

Generate a delivery blob of the specified delivery_type for data using default parameters.

generate_to

Generate a delivery blob of the specified delivery_type for data using default parameters and write the generated blob to writer.
