Crate ark_scale

Arkworks serialization wrapped in Parity SCALE codec

ArkScale(T) can be serialized or deserialized using parity-scale-codec, provided T can be serialized or deserialized using ark-serialize.

Arkworks serializes via the std::io::{Read,Write} traits, or its no_std fork of those traits, as do other zcash sapling derivatives. At its core, Parity SCALE codec also consists of traits {Input,Output} analogous to std::io::{Read,Write} respectively, as well as traits {Decode,Encode} also quite similar to ark-serialize::{CanonicalDeserialize,CanonicalSerialize}. We simply translate between these extremely similar traits, including wrapping and unwrapping errors appropriately.

Modules

• rw

Structs

• ArkScale
  Arkworks type wrapped for serialization by Scale
• ArkScaleRef

Constants

• HOST_CALL
  ArkScale usage which neither compresses nor validates inputs, only for usage in host calls where the runtime already performed validation checks.
• WIRE
  ArkScale usage for typical wire formats, like block data and gossip messages. Always safe.

Functions

• is_compressed
• is_validated
• iter_ark_to_ark_bytes
  Arkworks’ CanonicalSerialize cannot consume Iterators directly, but iter_ark_to_ark_bytes serializes exactly like Vec<T>, &'a [T], or [T] do with CanonicalSerialize.
• iter_ark_to_scale_bytes
  Arkworks’ CanonicalSerialize cannot consume Iterators directly, but iter_ark_to_scale_bytes serializes exactly like ArkScale(Vec<T>), ArkScale(&'a [T]), or ArkScale([T]) do under parity_scale_codec::Encode.
• make_usage
  Arkworks’ serialization modes hack.

Type Definitions

• Usage
  Arkworks’ serialization modes, morally (Compress, Validate) but const generics only supports integers, bool and char right now.
