[][src]Struct pallet_contracts::Config

pub struct Config<T: Trait> {

    pub tombstone_deposit: BalanceOf<T>,
    pub max_depth: u32,
    pub max_value_size: u32,
}

In-memory cache of configuration values.

We assume that these values can't be changed in the course of transaction execution.

Implementations

impl<T: Trait> Config<T>[src]

pub fn subsistence_threshold(&self) -> BalanceOf<T>[src]

Subsistence threshold is the extension of the minimum balance (aka existential deposit) by the tombstone deposit, required for leaving a tombstone.

Rent or any contract initiated balance transfer mechanism cannot make the balance lower than the subsistence threshold in order to guarantee that a tombstone is created.

The only way to completely kill a contract without a tombstone is calling seal_terminate.

pub fn subsistence_threshold_uncached() -> BalanceOf<T>[src]

The same as subsistence_threshold but without the need for a preloaded instance.

This is for cases where this value is needed in rent calculation rather than during contract execution.
