custom : (List U8, fmt -> List U8) -> Encoder fmt where fmt implements EncoderFormatting

Creates a custom encoder from a given function.

expect
    # Appends the byte 42
    customEncoder = Encode.custom (\bytes, _fmt -> List.append bytes 42)

    actual = Encode.appendWith [] customEncoder Core.json
    expected = [42] # Expected result is a list with a single byte, 42

    actual == expected

appendWith : List U8, Encoder fmt, fmt -> List U8 where fmt implements EncoderFormatting

append : List U8, val, fmt -> List U8 where val implements Encoding, fmt implements EncoderFormatting

Appends the encoded representation of a value to an existing list of bytes.

expect
    actual = Encode.append [] { foo: 43 } Core.json
    expected = Str.toUtf8 """{"foo":43}"""

    actual == expected

toBytes : val, fmt -> List U8 where val implements Encoding, fmt implements EncoderFormatting

Encodes a value to a list of bytes (List U8) according to the specified format.

expect
    fooRec = { foo: 42 }

    actual = Encode.toBytes fooRec Core.json
    expected = Str.toUtf8 """{"foo":42}"""

    actual == expected
