Overview

Package defers defines an Analyzer that checks for common mistakes in defer statements.

Analyzer defer

defer: report common mistakes in defer statements

The defer analyzer reports a diagnostic when a defer statement would result in a non-deferred call to time.Since, as experience has shown that this is nearly always a mistake.

For example:

start := time.Now()
...
defer recordLatency(time.Since(start)) // error: call to time.Since is not deferred

The correct code is:

defer func() { recordLatency(time.Since(start)) }()
