Ple Read Plan

struct PleReadSpan

Requested source bytes and their destination in a caller-owned packed buffer.

std::vector<PleReadSpan> const &spans,

std::vector<int64_t> const &shardEnds,

size_t alignment,

size_t maxReadBytes

)

Plan non-overlapping reads sorted by shard and offset, merging only aligned overlap or adjacency. Reads are alignment-sized except at shard ends, and no read exceeds maxReadBytes. Empty input returns no reads. Spans must be nonempty and fit their shard; destination regions must be distinct. alignment must be positive and maxReadBytes must be a positive multiple of it, both fitting INT64.
