Struct oasis_core_runtime::transaction::tags::Tag

pub struct Tag {
    pub key: Vec<u8>,
    pub value: Vec<u8>,
    pub tx_hash: Hash,
}

Tag is a key/value pair of arbitrary byte blobs with runtime-dependent semantics which can be indexed to allow easier lookup of blocks and transactions on runtime clients.

Fields

key: Vec<u8>

The tag key.

value: Vec<u8>

The tag value.

tx_hash: Hash

The hash of the transaction that emitted the tag.

Implementations

impl Tag

pub fn new(key: Vec<u8>, value: Vec<u8>) -> Self

Create a new tag.

The transaction hash is not initialized.

Trait Implementations

impl Clone for Tag

fn clone(&self) -> Tag

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Tag

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Tag

fn default() -> Tag

Returns the “default value” for a type.
