Crate deck_core 

deck-core — shared domain types, traits and configuration.

Every other deck-* crate depends on this one. We deliberately keep it free of heavy runtime deps (no tokio, no rusqlite, no ratatui) so that cargo check -p deck-core stays under a second.

Modules

config

User-facing configuration. Resolved from (precedence high → low):

error

Crate-wide error type. Libraries use thiserror for typed errors; the binary crate uses anyhow for application-level chaining.

message

Core message / session types that the orchestrator and TUI agree on.

traits

Backend-agnostic trait surface. Each deck-* crate is a concrete implementation of one or more of these traits; the orchestrator depends only on these abstractions.
