Enum ErrorCategory 

pub enum ErrorCategory {
    None,
    Config,
    Network,
    Crypto,
    Protocol,
    Identity,
    Storage,
    Trust,
    Internal,
}

ErrorCategory classifies an Error into the NWEP subsystem that produced it.

Each variant corresponds to a group of error codes sharing the same NWEP_ERR_CAT_* C constant. The category is determined automatically when constructing an Error via Error::from_code.

The Display implementation produces the lowercase subsystem name (e.g., "network", "crypto") which is suitable for logging and structured output.

Variants

None

None indicates no error (code zero) or an unrecognized category.

Config

Config groups errors related to configuration file parsing and validation.

Network

Network groups errors related to QUIC/UDP transport and socket operations.

Crypto

Crypto groups errors related to key generation, signing, verification, and TLS certificate handling.

Protocol

Protocol groups errors related to the NWEP application-layer protocol framing, headers, and method/status validation.

Identity

Identity groups errors related to node identity records, challenge authentication, and Shamir secret sharing.

Storage

Storage groups errors related to file I/O, key-value lookups, and data integrity.

Trust

Trust groups errors related to the distributed trust log, Merkle proofs, BLS checkpoints, and equivocation detection.

Internal

Internal groups errors that indicate bugs or unimplemented code paths inside the C library itself.

Trait Implementations

impl Clone for ErrorCategory

fn clone(&self) -> ErrorCategory

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErrorCategory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ErrorCategory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ErrorCategory

fn eq(&self, other: &ErrorCategory) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
