functions:
  vec_version:
    params: []
    section: meta
    desc: Returns a version string of the current `sqlite-vec` installation.
    example: select vec_version();
  vec_debug:
    params: []
    section: meta
    desc: Returns debugging information of the current `sqlite-vec` installation.
    example: select vec_debug();
  vec_bit:
    params: [vector]
    section: constructor
    desc: Creates a binary vector from a BLOB.
    example:
      - select vec_bit(X'F0');
      - select subtype(vec_bit(X'F0'));
      - select vec_to_json(vec_bit(X'F0'));
  vec_f32:
    params: [vector]
    section: constructor
    desc: |
      Creates a float vector from a BLOB or JSON text. If a BLOB is provided,
      the length must be divisible by 4, as a float takes up 4 bytes of space each.
    example:
      - select vec_float32('[.1, .2, .3, 4]');
      - select subtype(vec_float32('[.1, .2, .3, 4]'));
      - select vec_float32(X'AABBCCDD');
      - select vec_to_json(vec_float32(X'AABBCCDD'));
      - select vec_float32(X'AA');
  vec_int8:
    params: [vector]
    section: constructor
    desc:  |
      Creates a 8-bit integer vector from a BLOB or JSON text. If a BLOB is provided,
      the length must be divisible by 4, as a float takes up 4 bytes of space each.
      If JSON text is provided, each element must be an integer between -128 and 127 inclusive.

    example:
      - select vec_int8('[1, 2, 3, 4]');
      - select subtype(vec_int8('[1, 2, 3, 4]'));
      - select vec_int8(X'AABBCCDD');
      - select vec_to_json(vec_int8(X'AABBCCDD'));
      - select vec_int8('[999]');

  vec_add:
    params: [a, b]
    section: op
    desc: |
      Adds each element in vector `a` with vector `b`, returning a new vector `c`. Both vectors
      must be of the same type, and can only be a `float32` or `int8` vector.
    example: |
      - select vec_add(
          '[.1, .2, .3]',
          '[.4, .5, .6]'
        );
      - |
        select vec_to_json(
          vec_add(
            '[.1, .2, .3]',
            '[.4, .5, .6]'
          )
        );
      - |
        select vec_to_json(
          vec_int8('[1, 2, 3]'),
          vec_int8('[4, 5, 6]')
        )
