# Module frame_support::weights

source · ## Expand description

Re-exports `sp-weights`

public API, and contains benchmarked weight constants specific to FRAME.

## Modules

- These constants are specific to FRAME, and the current implementation of its various components. For example: FRAME System, FRAME Executive, our FRAME support libraries, etc…

## Structs

- Implementor of
`WeightToFee`

that uses a constant multiplier. - A list of coefficients that represent a polynomial.
- Implementor of
`WeightToFee`

that maps one unit of weight to one unit of fee. - OldWeightDeprecatedThe old weight type.
- The weight of database operations that the runtime can invoke.
- Meters consumed weight and a hard limit for the maximal consumable weight.
- One coefficient and its position in the
`WeightToFee`

.

## Traits
