Interface IBlobCodec

Binary BLOB codec for encoding/decoding vectors and computing hashes.

Node.js implementations use Buffer. Browser implementations use Uint8Array + DataView.

interface IBlobCodec {
    encode(vec: number[]): Uint8Array;
    decode(blob: Uint8Array | ArrayBufferLike): number[];
    sha256(input: string): Promise<string>;
}

Methods

encode

encode(vec): Uint8Array
Encode a number[] vector to a binary BLOB value (Float32 little-endian).

Returns Uint8Array
- Defined in src/core/contracts/blobCodec.ts:9

decode

decode(blob): number[]
Decode a BLOB column value back to number[].
Parameters
- blob: Uint8Array | ArrayBufferLike
Returns number[]
- Defined in src/core/contracts/blobCodec.ts:12

sha256

sha256(input): Promise<string>
SHA-256 hex digest. Async to support crypto.subtle in browsers.
Parameters
- input: string
Returns Promise<string>
