Module error 

Error type for the FROST-ed25519 scheme plugin.

The framework’s confium_tc::Error::SchemeInternalError carries a single u32 code; this module gives those codes stable, disambiguating values so a caller (or test) can tell a malformed commitment apart from a bad Lagrange weight. Codes are reported through the FFI as 0x1041 | sub, where sub is the FrostError::code of the underlying cause — they share the confium_tc::error::ErrorCode::SCHEME_INTERNAL_ERROR envelope but the low bits identify the FROST-specific failure.

Enums

FrostError

FROST-specific failure modes. Each variant maps to a distinct code so a failure cause can be identified without string-matching.

FROST_ERROR_BASE

Sub-range of error codes used by this scheme. The framework reports these via confium_tc::Error::SchemeInternalError’s code field. They begin at 0x2100 to avoid colliding with future schemes.
