Crate can_tools 

can_tools

Rust utilities for parsing and modeling automotive CAN data.

Highlights

• DBC parser: load CAN databases from .dbc into a SlotMap-backed Database.
• ASC parser: read Vector ASCII traces (.asc) into a decoupled CanLog.
• Stable keys: Nodes/Messages/Signals use SlotMap keys that remain valid across reordering.
• Ordered iteration: Database::iter_*() respects order vectors; use sort_*_by_name() to present alphabetically.
• Fast lookups: normalized helpers (get_message_by_id/_hex/_name, get_node_by_name, get_signal_by_name).
• Signal decoding: SignalDB::compile_inline, extract_raw_*, and to_sigframe.
