//! Structured error type returned by `manta-shared`'s pure helpers.
//!
//! Replaces the previous use of `manta_backend_dispatcher::error::Error`
//! in audit / jwt / kafka / config / sat-file / network-probe helpers,
//! so that this crate (and therefore `manta-cli`) no longer needs to
//! reach into backend-dispatcher types for its error surface.
//!
//! Server-side code keeps returning `manta_backend_dispatcher::error::Error`
//! and uses `?` to convert `MantaError` at the call site via the
//! `From<MantaError> for BackendError` impl in
//! `crates/manta-server/src/wire_conv.rs`.
