Reads an Integer value from source with a specified tag under the specified encoding rules, returning the contents as a slice of the buffer.

- source
- ReadOnlySpan<Byte>
The buffer containing encoded data.
- ruleSet
- AsnEncodingRules
The encoding constraints to use when interpreting the data.
- bytesConsumed
- Int32
When this method returns, the total number of bytes for the encoded value. This parameter is treated as uninitialized.
The tag to check for before reading, or null for the default tag (Universal 2).
Returns
The slice of the buffer containing the bytes of the Integer value, in signed big-endian form.
Exceptions
ruleSet is not defined.
The next value does not have the correct tag.
-or-
The length encoding is not valid under the current encoding rules.
-or-
The contents are not valid under the current encoding rules.
