Represents a chunk of text from a document, used for processing long documents.

## Fields

* `:text` - The chunk text content
* `:document` - Reference to source document
* `:token_interval` - Token range in original document
* `:char_interval` - Character range in original document
* `:chunk_index` - Position in sequence of chunks

## Examples

    iex> chunk = %LeXtract.TextChunk{
    ...>   text: "Sample chunk",
    ...>   chunk_index: 0
    ...> }
    iex> chunk.chunk_index
    0

# `t`

```elixir
@type t() :: %LeXtract.TextChunk{
  char_interval: LeXtract.CharInterval.t() | nil,
  chunk_index: non_neg_integer() | nil,
  document: LeXtract.Document.t() | nil,
  text: String.t(),
  token_interval: LeXtract.TokenInterval.t() | nil
}
```

# `char_count`

```elixir
@spec char_count(t()) :: non_neg_integer()
```

Returns the character count of the chunk text.

## Examples

    iex> chunk = %LeXtract.TextChunk{text: "Hello"}
    iex> LeXtract.TextChunk.char_count(chunk)
    5

# `text_byte_size`

```elixir
@spec text_byte_size(t()) :: non_neg_integer()
```

Returns the byte size of the chunk text.

## Examples

    iex> chunk = %LeXtract.TextChunk{text: "Hello"}
    iex> LeXtract.TextChunk.text_byte_size(chunk)
