Using the sample below,
we are going to illustrate how to extract the data that we want using the Ruby Client Library.

Quick-Start

#
# Install the Ruby client library by running:
# gem install mindee
#

require 'mindee'

# Init a new client
mindee_client = Mindee::Client.new(api_key: 'my-api-key')

# Load a file from disk
input_source = mindee_client.source_from_path('/path/to/the/file.ext')

# Parse the file
result = mindee_client.parse(
  input_source,
  Mindee::Product::FR::IdCard::IdCardV2
)

# Print a full summary of the parsed data in RST format
puts result.document

# Print the document-level parsed data
# puts result.document.inference.prediction

Output (RST):

### Date Field
Aside from the basic `Field` attributes, the date field `DateField` also implements the following:

* **date_object** (`Date`): an accessible representation of the value as a JavaScript object.

### String Field
The text field `StringField` only has one constraint: it's **value** is a `String` (or `nil`).

## Page-Level Fields
Some fields are constrained to the page level, and so will not be retrievable at document level.

# Attributes
