The CI lint job runs clippy with -D warnings, which surfaced a set of
existing warnings across decoders, the client, and the soapysdr backend.
Resolve them so the workspace is clean under the enforced lint level:
- collapsible_match / identity_op / needless_range_loop / same_item_push
in trx-rds, trx-wspr, trx-vdes, trx-wefax, trx-aprs (mostly tests)
- field_reassign_with_default -> struct-update syntax in trx-client config
tests
- assign_op_pattern, useless vec!, and test-module ordering picked up by
cargo clippy --fix in trx-client and the soapysdr WFM tests
No behaviour changes; all affected crates' tests pass.
