View Source Peri.Parser (peri v0.2.6)

The Peri.Parser module is responsible for managing the state during schema validation. It centralizes functions to handle updating data, adding errors, and managing the path within the data structure being validated.

Struct

The Peri.Parser struct has the following fields:

:data - The current state of the data being validated.
:errors - A list of errors encountered during validation.
:path - The current path within the data structure being validated.

Summary

Functions

add_error(state, err)

Adds an error to the parser state's list of errors.

new(data)

Initializes a new Peri.Parser struct with the given data.

update_data(state, key, val)

Updates the data in the parser state at the given key with the specified value.

Functions

add_error(state, err)

Adds an error to the parser state's list of errors.

Parameters

state - The current Peri.Parser state.
err - The %Peri.Error{} struct representing the error to add.

Examples

iex> state = Peri.Parser.new(%{name: "Alice"})
iex> error = %Peri.Error{path: [:name], message: "is required", content: []}
iex> Peri.Parser.add_error(state, error)
%Peri.Parser{data: %{name: "Alice"}, errors: [%Peri.Error{path: [:name], message: "is required", content: []}], path: []}

new(data)

Initializes a new Peri.Parser struct with the given data.

Parameters

data - The initial data to be validated.

Examples

iex> Peri.Parser.new(%{name: "Alice"})
%Peri.Parser{data: %{name: "Alice"}, errors: [], path: []}

update_data(state, key, val)

Updates the data in the parser state at the given key with the specified value.

Parameters

state - The current Peri.Parser state.
key - The key to update in the data.
val - The value to set at the specified key.

Examples

iex> state = Peri.Parser.new(%{name: "Alice"})
iex> Peri.Parser.update_data(state, :age, 30)
%Peri.Parser{data: %{name: "Alice", age: 30}, errors: [], path: []}
