Introduces a keygen-specific trait and a struct within to manage common state (params, data, channels, etc.) and round transitions independently of the core traits. Also includes: - Definition of enum for specific error handling. - Updates to message structs to implement . - Replacement of ECDSA/Paillier placeholders with EdDSA/VSS/Schnorr types/placeholders. - Updates to for EdDSA. - Implementation of for . - General import fixes and module structure adjustments. --- tss-lib-rust/src/eddsa/keygen/error.rs | 74 ++ tss-lib-rust/src/eddsa/keygen/local_party.rs | 972 +++++-------------- tss-lib-rust/src/eddsa/keygen/messages.rs | 346 +++---- tss-lib-rust/src/eddsa/keygen/mod.rs | 15 + tss-lib-rust/src/eddsa/keygen/params.rs | 68 ++ tss-lib-rust/src/eddsa/keygen/party_base.rs | 244 +++++ tss-lib-rust/src/eddsa/keygen/round_1.rs | 354 +++---- tss-lib-rust/src/eddsa/keygen/round_2.rs | 472 ++++----- tss-lib-rust/src/eddsa/keygen/round_3.rs | 259 ++--- tss-lib-rust/src/eddsa/keygen/rounds.rs | 108 ++- tss-lib-rust/src/eddsa/keygen/save_data.rs | 204 ++-- tss-lib-rust/src/eddsa/keygen/test_utils.rs | 53 +- tss-lib-rust/src/eddsa/mod.rs | 4 + tss-lib-rust/src/lib.rs | 1 + tss-lib-rust/src/tss/curve.rs | 9 +- tss-lib-rust/src/tss/party_id.rs | 9 + 16 files changed, 1458 insertions(+), 1734 deletions(-) create mode 100644 tss-lib-rust/src/eddsa/keygen/error.rs create mode 100644 tss-lib-rust/src/eddsa/keygen/params.rs create mode 100644 tss-lib-rust/src/eddsa/keygen/party_base.rs create mode 100644 tss-lib-rust/src/eddsa/mod.rs diff --git a/tss-lib-rust/src/eddsa/keygen/error.rs b/tss-lib-rust/src/eddsa/keygen/error.rs new file mode 100644 index 00000000..2928333e --- /dev/null +++ b/tss-lib-rust/src/eddsa/keygen/error.rs @@ -0,0 +1,74 @@ +// Keygen specific errors + +use std::fmt;
