Compare two POD5 collections or manifests — pod5

pod5_compare() compares two local POD5 files, folders, run trees, or pod5-tools manifest JSON files through the in-process Rust extension. It is designed for operational handoff checks: missing files and changed file-size or verification-state differences are returned as rows rather than rendered text.

Usage

pod5_compare(left, right)

Arguments

left, right: Character scalars. POD5 inputs or manifest JSON files to compare.

Value

A data frame with the columns status, kind, relative_path, left_size_bytes, right_size_bytes, left_verification_status, and right_verification_status. Matching inputs return one row with status = "match" and kind = "match".

Examples

signature <- as.raw(c(0x8b, 0x50, 0x4f, 0x44, 0x0d, 0x0a, 0x1a, 0x0a))
left <- file.path(tempdir(), "flounder-compare-left")
right <- file.path(tempdir(), "flounder-compare-right")
unlink(c(left, right), recursive = TRUE)
dir.create(left, recursive = TRUE)
dir.create(right, recursive = TRUE)
writeBin(c(signature, as.raw(rep(0, 16)), signature), file.path(left, "a.pod5"))
writeBin(c(signature, as.raw(rep(1, 16)), signature), file.path(right, "a.pod5"))
