Expand description
Information concerning a valid transaction.
Fields§
§priority: u64
Priority of the transaction.
Priority determines the ordering of two transactions that have all their dependencies (required tags) satisfied.
requires: Vec<Vec<u8>>
Transaction dependencies
A non-empty list signifies that some other transactions which provide given tags are required to be included before that one.
provides: Vec<Vec<u8>>
Provided tags
A list of tags this transaction provides. Successfully importing the transaction will enable other transactions that depend on (require) those tags to be included as well. Provided and required tags allow Substrate to build a dependency graph of transactions and import them in the right (linear) order.
longevity: u64
Transaction longevity
Longevity describes minimum number of blocks the validity is correct. After this period transaction should be removed from the pool or revalidated.
propagate: bool
A flag indicating if the transaction should be propagated to other peers.
By setting false
here the transaction will still be considered for
including in blocks that are authored on the current node, but will
never be sent to other peers.
Implementations§
source§impl ValidTransaction
impl ValidTransaction
sourcepub fn with_tag_prefix(prefix: &'static str) -> ValidTransactionBuilder
pub fn with_tag_prefix(prefix: &'static str) -> ValidTransactionBuilder
Initiate ValidTransaction
builder object with a particular prefix for tags.
To avoid conflicts between different parts in runtime it’s recommended to build requires
and provides
tags with a unique prefix.
sourcepub fn combine_with(self, other: ValidTransaction) -> ValidTransaction
pub fn combine_with(self, other: ValidTransaction) -> ValidTransaction
Combine two instances into one, as a best effort. This will take the superset of each of the
provides
and requires
tags, it will sum the priorities, take the minimum longevity and
the logic And of the propagate flags.
