pub struct Metadata {
pub entries: Vec<(u64, TransactionMetadatum)>,
pub encodings: Option<MetadataEncoding>,
}
Expand description
Collection of TransactionMetadatums indexed by TransactionMetadatumLabels Handles the extremely rare edge-case of in previous generations allowing duplicate metadatum labels.
Fields§
§entries: Vec<(u64, TransactionMetadatum)>
§encodings: Option<MetadataEncoding>
Implementations§
source§impl Metadata
impl Metadata
pub fn new() -> Metadata
pub fn len(&self) -> usize
pub fn is_empty(&self) -> bool
sourcepub fn set(&mut self, label: u64, datum: TransactionMetadatum)
pub fn set(&mut self, label: u64, datum: TransactionMetadatum)
Replaces all metadatums of a given label, if any exist.
sourcepub fn get(&self, label: u64) -> Option<&TransactionMetadatum>
pub fn get(&self, label: u64) -> Option<&TransactionMetadatum>
Gets the Metadatum corresponding to a given label, if it exists. Note: In the case of duplicate labels this only returns the first metadatum. This is an extremely rare occurence on-chain but can happen.

fn to_cbor_bytes(&self) -> Vec<u8> ⓘ
Bytes of a structure using the CBOR bytes as per the CDDL spec
which for foo = bytes will include the CBOR bytes type/len, etc.
This gives the original bytes in the case where this was created
from bytes originally, or will use whatever the specific encoding
details are present in any encoding details struct for the type.
