Compares two tag collections for equality.

The first collection of tags. it has to be a sorted List The second collection of tags. This one doesn't have to be sorted nor be specific collection type True if the two collections are equal, false otherwise This method is used to compare two collections of tags for equality. The first collection is expected to be a sorted array of tags. The second collection can be any collection of tags. we avoid the allocation of a new array by using the second collection as is and not converting it to an array. the reason is we call this every time we try to create a meter or instrument and we don't want to allocate a new array every time.

Gets the associated parameter name.

Applied to a method that will never return under any circumstance.

Initializes the attribute with the specified parameter value.

Attribute used to indicate a source generator should create a function for marshalling arguments instead of relying on the runtime to generate an equivalent marshalling function at run-time.

This attribute is meaningless if the source generator associated with it is not enabled. The current built-in source generator only supports C# and only supplies an implementation when applied to static, partial, non-generic methods.

Initializes a new instance of the .
