pub struct BlockWeightsBuilder { /* private fields */ }

Expand description

An opinionated builder for Weights object.

Implementations

source

impl BlockWeightsBuilder

source

pub fn base_block(self, base_block: Weight) -> Self

Set base block weight.

source

pub fn avg_block_initialization(self, init_cost: Perbill) -> Self

Average block initialization weight cost.

This value is used to derive maximal allowed extrinsic weight for each class, based on the allowance.

This is to make sure that extrinsics don’t stay forever in the pool, because they could seamingly fit the block (since they are below max_block), but the cost of calling on_initialize always prevents them from being included.

source

pub fn for_class(
 self,
 class: impl OneOrMany<DispatchClass>,
 action: impl Fn(&mut WeightsPerClass)
) -> Self

Set parameters for particular class.

Note: None values of max_extrinsic will be overwritten in build in case avg_block_initialization rate is set to a non-zero value.

source

pub fn build(self) -> ValidationResult

Construct the BlockWeights object.

source

pub fn build_or_panic(self) -> BlockWeights

Construct the BlockWeights object or panic if it’s invalid.

This is a convenience method to be called whenever you construct a runtime.

T: Any,

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more
