strong

An enumeration of the types of Extended JSON that the to_json function accepts.

Enumerator
k_legacy	to produce Legacy Extended JSON
k_canonical	to produce Canonical Extended JSON
k_relaxed	to produce Relaxed Extended JSON

◆ type

enum bsoncxx::v_noabi::type : std::uint8_t

strong

These x-macros will expand to be of the form: k_double = 0x01, k_string = 0x02, k_document = 0x03, k_array = 0x04 ...

Function Documentation

◆ error_category()

const std::error_category& bsoncxx::v_noabi::error_category ( )

Get the error_category for exceptions originating from the bsoncxx library.

Returns: The bsoncxx error_category

◆ from_json()

document::value bsoncxx::v_noabi::from_json ( stdx::string_view json )

Constructs a new document::value from the provided JSON text.

Parameters

'json' A string_view into a JSON document.

Returns: A document::value if conversion worked.

Exceptions

bsoncxx::v_noabi::exception with error details if the conversion failed.

◆ make_error_code()

std::error_code bsoncxx::v_noabi::make_error_code ( error_code error )

Translate a bsoncxx::v_noabi::error_code into a std::error_code.

Parameters

error An error from bsoncxx

Returns: An error_code

◆ operator""_bson()

document::value bsoncxx::v_noabi::operator""_bson	(	const char *	json,
		size_t	len
	)

Constructs a new document::value from the provided JSON text.

This is the UDL version of from_json().

Parameters

'json'	A string into a JSON document.
'len'	The length of the JSON string. This is calculated automatically upon use of the UDL.

Returns: A document::value if conversion worked.

Exceptions

bsoncxx::v_noabi::exception with error details if the conversion failed.

◆ to_json()

std::string bsoncxx::v_noabi::to_json	(	document::view	view,
		ExtendedJsonMode	mode = `ExtendedJsonMode::k_legacy`
	)

Converts a BSON document to a JSON string, in extended format.

Parameters

view	A valid BSON document.
mode	An optional JSON representation mode.

Exceptions

bsoncxx::v_noabi::exception with error details if the conversion failed.

Returns: An extended JSON string.

◆ to_string() [1/2]

std::string bsoncxx::v_noabi::to_string ( binary_sub_type rhs )

Returns a stringification of the given binary sub type.

Parameters

rhs	The type to stringify.

Returns: a std::string representation of the type.

◆ to_string() [2/2]

std::string bsoncxx::v_noabi::to_string ( type rhs )

Returns a stringification of the given type.

Parameters

rhs	The type to stringify.

Returns: a std::string representation of the type.

◆ validate() [1/2]

stdx::optional<document::view> bsoncxx::v_noabi::validate	(	const std::uint8_t *	data,
		std::size_t	length
	)

Validates a BSON document.

This is a simplified overload that will only do the bare minimum validation of document structure, and does not provide any further information if the document is found to be invalid.

Parameters

data	A buffer containing a BSON document to validate.
length	The size of the buffer.

Returns: An engaged optional containing a view if the document is valid, or an unengaged optional if the document is invalid.

◆ validate() [2/2]

stdx::optional<document::view> bsoncxx::v_noabi::validate	(	const std::uint8_t *	data,
		std::size_t	length,
		const validator &	validator,
		std::size_t *	invalid_offset = `nullptr`
	)

Validates a BSON document.

This overload provides additional control over the precise validation that is performed, and will give the caller access to the offset at which the document was found to be invalid.

Parameters

data	A buffer containing a BSON document to validate.
length	The size of the buffer.
validator	A validator used to configure what checks are done. If validation fails, it will contain the offset at which the document was found to be invalid.
invalid_offset	If validation fails, the offset at which the document was found to be invalid will be stored here (if non-null).

Returns: An engaged optional containing a view if the document is valid, or an unengaged optional if the document is invalid.
