propagate_(transcode|transcode)_error

This helper function processes an error for a transcoding operation and shuffles a result through its decode step and encode step error handlers. Nominally used after a solely decode portion of a transcode operation fails.

If the user is doing a direct conversion and can simply call the encode portion of the error handler directly, calling this function can be skipped entirely by the user.

Transcoding helper. Takes the given __from_encoding, __to_encoding, __encode_error_handler, and __decode_error_handler and launders the ztd::text::encode_result through the __encode_error_handler. The transformed encode result is then transformed to a ztd::text::decode_result before transforming that into the desired ztd::text::recode_result type.

Remark

This function is a helper whose sole purpose is to ensure that the other half of error handling is called by recode-style functions written by the end user (e.g., writing overriding hooks for ztd::text::recode). This function attempts to take care of any unread/unwritten characters and other minor points in its pursuit of properly making sure the error manifests on the other side.

Transcoding helper. Takes the given __from_encoding, __to_encoding, __decode_error_handler, and __encode_error_handler and launders the ztd::text::decode_result through the __decode_error_handler. The transformed decode result is then transformed to a ztd::text::encode_result before transforming that into the desired ztd::text::transcode_result type.

Remark

This function is a helper whose sole purpose is to ensure that the other half of error handling is called by transcode-style functions written by the end user (e.g., writing overriding hooks for ztd::text::transcode). This function attempts to take care of any unread/unwritten characters and other minor points in its pursuit of properly making sure the error manifests on the other side.

Template Parameters:

_Result – The exact transcode result type to use.

Parameters:

__output – [in] The output view to be writing into.
__from_encoding – [in] The desired encoding that performs the encode portion of the transcoding step.
__to_encoding – [in] The desired encoding that performs the encode portion of the transcoding step.
__decode_result – [in] The decode result value that has an error on it.
__decode_error_handler – [in] The error handler to mill the __result and other relevant information through.
__encode_error_handler – [in] The error handler to mill the __decode_error_handler’s invoked result and other relevant information through.
__to_state – [in] The current state of the encoding step of the transcode operation.
__to_input_progress – [in] Any unread output characters in any intermediate between the (failed) decode and encode operations.
__to_output_progress – [in] Any unread output characters in any intermediates between the (failed) decode and encode operations.

Transcoding helper. Takes the given __to_encoding and __encode_error_handler and launders the failed ztd::text::decode_result through it, producing a ztd::text::encode_result and transforming that into the desired ztd::text::transcode_result type.

Takes the given __to_encoding and __encode_error_handler and launders the failed ztd::text::decode_result through it, producing a ztd::text::encode_result and transforming that into the desired ztd::text::transcode_result type.

Remark

This function is a helper whose sole purpose is to ensure that the other half of error handling is called by transcode-style functions written by the end user (e.g., writing overriding hooks for ztd::text::transcode). This function attempts to take care of any unread/unwritten characters and other minor points in its pursuit of properly making sure the error manifests on the other side. Unlike it’s counterpart, this function does not take an _Result template parameter and instead deduces the returned transcode result type from inputs.

Parameters:

__output – [in] The input view to be reading from.
__output – [in] The output view to be writing into.
__to_encoding – [in] The desired encoding that performs the encode portion of the transcoding step.
__decode_result – [in] The decode result value that has an error on it.
__encode_result – [in] The encode result value that represents .
__encode_error_handler – [in] The error handler to mill the __result and other relevant information through.
__to_state – [in] The current state of the encoding step of the transcode operation.
__to_input_progress – [in] Any unread output characters in any intermediate between the (failed) decode and encode operations.
__to_output_progress – [in] Any unread output characters in any intermediates between the (failed) decode and encode operations.
