box.error.new()

box.error.new({ reason = string[, code = number, type = string] }])¶

Create an error object with the specified parameters.

Параметры:	reason (string) – an error description code (integer) – (optional) a numeric code for this error type (string) – (optional) an error type

Example 1

local custom_error = box.error.new({ code = 500,
                                     reason = 'Internal server error' })

box.error(custom_error)
--[[
---
- error: Internal server error
...
--]]

Example 2: custom type

local custom_error = box.error.new({ code = 500,
                                     reason = 'Internal server error',
                                     type = 'CustomInternalError' })

box.error(custom_error)
--[[
---
- error: Internal server error
...
--]]

box.error.new(type, reason[, ...])

Create an error object with the specified type and description.

Параметры:	type (string) – an error type reason (string) – an error description ... – description arguments

Example

local custom_error = box.error.new('CustomInternalError', 'Internal server error')

box.error(custom_error)
--[[
---
- error: Internal server error
...
--]]

box.error.new(code[, ...])

Create a predefined Tarantool error specified by its identifier. You can see all Tarantool errors in the errcode.h file.

Параметры:	code (number) – a pre-defined error identifier; Lua constants that correspond to those Tarantool errors are defined as members of box.error, for example, box.error.NO_SUCH_USER == 45 ... – description arguments

Example 1: one argument

local custom_error = box.error.new(box.error.NO_SUCH_USER, 'John')

box.error(custom_error)
--[[
---
- error: User 'John' is not found
...
--]]

Example 2: two arguments

local custom_error = box.error.new(box.error.CREATE_SPACE, 'my_space', 'the space already exists')

box.error(custom_error)
--[[
---
- error: 'Failed to create space ''my_space'': the space already exists'
...
--]]
