chunkLayout
chunkLayout(
ciphertextSize,chunkSize):ChunkLayout
Defined in: packages/filecoin-encryption-envelope/src/chunk-layout.ts:27
Derive the chunk layout of a stored blob from its ciphertext size and
chunk size — never the reverse. A declared chunk_count header must be
checked against chunkLayout(...).chunkCount, not the other way around,
or a truncated object would go undetected (docs/tech-spec.md, “Three
rules make the check correct”).
