Enum sp_runtime::generic::Era[][src]

pub enum Era {
    Immortal,
    Mortal(u64Phase),
}

An era to describe the longevity of a transaction.

Variants

Immortal

The transaction is valid forever. The genesis hash must be present in the signed content.

Mortal(u64Phase)

Period and phase are encoded:

When used on FRAME-based runtimes, period cannot exceed BlockHashCount parameter of system module.

Implementations

impl Era[src]

pub fn mortal(period: u64, current: u64) -> Self[src]

Create a new era based on a period (which should be a power of two between 4 and 65536 inclusive) and a block number on which it should start (or, for long periods, be shortly after the start).

If using Era in the context of FRAME runtime, make sure that period does not exceed BlockHashCount parameter passed to system module, since that prunes old blocks and renders transactions immediately invalid.

pub fn immortal() -> Self[src]

Create an “immortal” transaction.

pub fn is_immortal(&self) -> bool[src]

true if this is an immortal transaction.

pub fn birth(self, current: u64) -> u64[src]

Get the block number of the start of the era whose properties this object describes that current belongs to.

pub fn death(self, current: u64) -> u64[src]

Get the block number of the first block at which the era has ended.
