Enum sp_runtime::generic::Era
source · pub enum Era {
Immortal,
Mortal(u64, Phase),
}
Expand description
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(u64, Phase)
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.
Implementations§
source§impl Era
impl Era
sourcepub fn mortal(period: u64, current: u64) -> Self
pub fn mortal(period: u64, current: u64) -> Self
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.
sourcepub fn is_immortal(&self) -> bool
pub fn is_immortal(&self) -> bool
true
if this is an immortal transaction.
