Handling errors
Most crate functions mentioned below return Results with
Errors.
All errors should be considered fatal and should lead to aborting the key
generation or signing procedure.
Serializing structures
FROST is a distributed protocol and thus it requires sending messages between participants. While the ZF FROST library does not handle communication, it can help with serialization in the following ways:
Default byte-oriented serialization
With the serialization feature, which is enabled by default, all structs that
need to communicated will have serialize() and deserialize() methods. The
serialization format is described in Serialization
Format.
serde
Alternatively, if you would like to user another format such as JSON, you can
enable the serde feature (which is not enabled by default). When it is
enabled, you can use serde to serialize any structure that
needs to be transmitted. The importing would look like:
[dependencies]
frost-ristretto255 = { version = "0.7.0", features = ["serde"] }
Note that serde usage is optional. Applications can use different encodings, and
to support that, all structures that need to be transmitted have public getters
and new() methods allowing the application to encode and decode them as it
wishes. (Note that fields like Scalar and Element do have standard byte
string encodings; the application can encode those byte strings as it wishes, as
well the structure themselves and things like maps and lists.)
