Functions

d

Decode a single variable-byte encoded integer from the input. Returns the value and the number of bytes consumed.

d_diffdiff

Decodes a sequence of integers encoded with e_diff. Reconstructs the original increasing sequence from the differences.

d_li

Decodes a list of variable-byte encoded integers from the input.

d_offset

Decode a single variable-byte encoded integer from the buffer at the given offset. Updates the offset to point after the decoded value. Highly optimized with unsafe pointer arithmetic and bounds check elimination.

e

Encodes a single u64 into variable-byte format and appends to the buffer. This function does not clear the buffer; it appends the encoded bytes to the end. Optimized to avoid repeated capacity checks and len updates.

e_diffdiff

Encodes a strictly increasing sequence of u64 integers using differential encoding (delta encoding) combined with variable-byte encoding. This reduces the serialized size by storing the differences between consecutive values.

e_li

Encodes a list of u64 integers into variable-byte format.
