[−][src]Enum sp_runtime::generic::Era
An era to describe the longevity of a transaction.
Variants
The transaction is valid forever. The genesis hash must be present in the signed content.
Period and phase are encoded:
- The period of validity from the block hash found in the signing material.
- The phase in the period that this transaction's lifetime begins (and, importantly,
implies which block hash is included in the signature material). If the
period
is greater than 1 << 12, then it will be a factor of the times greater than 1<<12 thatperiod
is.
When used on FRAME
-based runtimes, period
cannot exceed BlockHashCount
parameter
of system
module.
Methods
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.
