Module indexed 

Tables of records an index found: the messages of one type in a flight log, the frames of one CAN message in a candump.

A log interleaves its message types, so where the rows of one type are is not arithmetic. One pass over the file records where each record of each type starts (Offsets); a table is then decoded from a map of the file at those offsets through the decode core of the binary format specs (crate::fixed_records), only the rows and columns a view reaches. The pass’s result is kept (cached), so the home screen can list a log’s tables and each opens without reading the file again.

Structs

IndexedRecords

The records of one type: fixed columns at offsets into each record.

Enums

Offsets

Where each record of one type starts, four bytes a record when the file allows.

Constants

MAX_RECORDS

Records one pass indexes, all types together. Four bytes a record for a file under 4 GiB, eight past it: 256 MiB at most for a file under 4 GiB.

Functions

cached

The index of path: the one kept, or build’s, which is then kept.

forget

Let go of the index of path kept for type T.

keep

Keep index as the one of path, in place of any kept before.

peek

The index of path a pass already made, while the file is as it was.
