@callback after_resolution(execution :: Absinthe.Blueprint.Execution.t()) :: Absinthe.Blueprint.Execution.t()
callback to do something with the resolution accumulator after resolution.
NOTE: This function is given the full accumulator. Namespacing is suggested to avoid conflicts.
@callback before_resolution(execution :: Absinthe.Blueprint.Execution.t()) :: Absinthe.Blueprint.Execution.t()
callback to setup the resolution accumulator prior to resolution.
NOTE: This function is given the full accumulator. Namespacing is suggested to avoid conflicts.
@callback pipeline( next_pipeline :: Absinthe.Pipeline.t(), execution :: Absinthe.Blueprint.Execution.t() ) :: Absinthe.Pipeline.t()
callback used to specify additional phases to run.
Plugins may require additional resolution phases to be run. This function should use values set in the resolution accumulator to determine whether or not additional phases are required.
NOTE: This function is given the whole pipeline to be inserted after the current phase completes.
