Struct MemoryBudget 

pub struct MemoryBudget {
    pub block_cache: u64,
    pub dict_cache: u64,
    pub tile_cache: u64,
}

How a total --memory-budget-mb splits across the export’s three bounded consumers. The window’s per-row string buffer and the id buffer are small (bounded by the fixed window row count, not the file), so they are left in the slack between this sum and the total rather than given a named cap; peak RSS is therefore ≈ total + window_string_buffer + fixed open overhead.

Fields

block_cache: u64

Raw file-block LRU (the BlockCacheReader that backs the ranged reader).

dict_cache: u64

Decompressed dictionary chunk bodies (the old ~4.3 GB export floor).

tile_cache: u64

Decoded index tiles of the scanned permutation.
