Timber v3.0.0-alpha.2 Timber.Contextable protocol View Source
Converts a data structure into a Timber.Context.t
. This is called on any data structure passed
in the Timber.add_context/1
function.
For example, this protocol is how we’re able to support Keyword.t
types:
Timber.add_context(build: %{version: "1.0"})
This is achieved by:
defimpl Timber.Contextable, for: Map do
def to_context(map) when map_size(map) == 1 do
[type] = Map.keys(map)
[data] = Map.values(map)
%Timber.Contexts.CustomContext{
type: type,
data: data
}
end
end
What about custom contexts and structs?
We recommend defining a struct and calling use Timber.Contexts.CustomContext
in that module.
This takes care of everything automatically. See Timber.Contexts.CustomContext
for examples.
