See Benchee.Conversion.Count and Benchee.Conversion.Duration for examples.

format_human(number)

Callbacks

format(number)

@callback format(number()) :: String.t()

So instead of 1.5h it says 1h 30min

Functions

format(arg)

Formats a unit value in the domain described by module. The module should provide a units/0 function that returns a Map like

%{ :unit_name => %Benchee.Conversion.Unit{ ... } }

Additionally, module may specify a separator/0 function, which provides a custom separator string that will appear between the value and label in the formatted output. If no separator/0 function exists, the default separator (a single space) will be used.

iex> format({1.0, :kilobyte}, Benchee.Conversion.Memory)
"1 KB"

format(number, module)

format(number, label, separator)

Formats a unit value with specified label and separator

format_human(number, module)

Human friendly duration format for time as a string.

The output is a sequence of values and unit labels separated by a space. Only units whose value is non-zero are included in the output. The passed number is duration in the base unit - nanoseconds.
