Validates values against type definitions and schemas.
This module provides the core validation logic for Exdantic schemas, handling field validation, constraints, and error reporting.
Summary
Functions
Validates a value against a type definition.
Validates data against a schema module, checking for required fields, field-level validations, and strict mode constraints if enabled.
Types
@type validation_result() :: {:ok, term()} | {:error, Exdantic.Error.t() | [Exdantic.Error.t()]}
Functions
@spec validate(Exdantic.Types.type_definition() | module(), term()) :: validation_result()
@spec validate(Exdantic.Types.type_definition() | module(), term(), validation_path()) :: validation_result()
Validates a value against a type definition.
Parameters
type- The type definition or schema module to validate againstvalue- The value to validatepath- Current validation path for error messages (defaults to[])
Returns
{:ok, validated_value}on success{:error, errors}on validation failures
Examples
iex> Exdantic.Validator.validate({:type, :string, []}, "hello")
{:ok, "hello"}
iex> Exdantic.Validator.validate({:type, :integer, []}, "not a number")
{:error, %Exdantic.Error{...}}@spec validate_schema(module(), map(), validation_path()) :: validation_result()
Validates data against a schema module, checking for required fields, field-level validations, and strict mode constraints if enabled.
Parameters
schema- Schema module to validate againstdata- Data to validate (map)path- Current validation path for error messages (defaults to[])
Returns
{:ok, validated_data}on success{:error, errors}on validation failures
Examples
iex> defmodule TestSchema do
...> use Exdantic
...> schema do
...> field :name, :string
...> end
...> end
iex> Exdantic.Validator.validate_schema(TestSchema, %{name: "John"})
{:ok, %{name: "John"}}
