Package metadata
Package metadata is a way of defining message headers
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.
func NewContext(ctx context.Context, md Metadata) context.Context
Metadata is our way of representing request headers internally.
They're used at the RPC level and translate back and forth
from Transport headers.
type Metadata map[string]string
func FromContext(ctx context.Context) (Metadata, bool)
