Also, the best approach was to use already existing standards.

So, before even starting to code **FastAPI**, I spent several months studying the specs for OpenAPI, JSON Schema, OAuth2, etc. Understanding their relationship, overlap, and differences.

## Design

Then I spent some time designing the developer "API" I wanted to have as a user (as a developer using FastAPI).

	// on and then pick up on the frame offsets of specific

	// Stack slot merging is a greedy algorithm, and there can
	// be many possible ways to overlap a given set of candidate
	// variables, all of them legal. Rather than locking down
	// a specific set of overlappings or frame offsets, this
	// tests just verifies that there is a decent-sized clump of 4+ vars that

'*.' can be used to encrypt all resource in the core group.  '*.*' will encrypt all
resources, even custom resources that are added after API server start.
Use of wildcards that overlap within the same resource list or across multiple
entries are not allowed since part of the configuration would be ineffective.
Resource lists are processed in order, with earlier lists taking precedence.

Example:

	SyscallTime       time.Duration
	SyscallBlockTime  time.Duration

	// TotalTime is the duration of the goroutine's presence in the trace.
	// Necessarily overlaps with other stats.
	TotalTime time.Duration

	// Total time the goroutine spent in certain ranges; may overlap
	// with other stats.
	RangeTime map[string]time.Duration
}

func (s GoroutineExecStats) NonOverlappingStats() map[string]time.Duration {
