Package unusedresult
import "cmd/vendor/golang.org/x/tools/go/analysis/passes/unusedresult"
- Overview
- Index
Package unusedresult defines an analyzer that checks for unused
results of calls to certain pure functions.
In the call graph viewer below, each node
is a function belonging to this package
and its children are the functions it
calls—perhaps dynamically.
The root nodes are the entry points of the
package: functions that may be called from
outside the package.
There may be non-exported or anonymous
functions among them if they are called
dynamically from another package.
Click a node to visit that function's source code.
From there you can visit its callers by
clicking its declaring func
token.
Functions may be omitted if they were
determined to be unreachable in the
particular programs or tests that were
analyzed.
Constants
const Doc = `check for unused results of calls to some functions
Some functions like fmt.Errorf return a result and have no side effects,
so it is always a mistake to discard the result. This analyzer reports
calls to certain functions in which the result of the call is ignored.
The set of functions may be controlled using flags.`
