Remarks
This function parses a statement URI and separates it into its constituent identifier and digest components. It expects the URI to conform to a specific format and structure.
Example
const statementUri = 'stmt:cord:1234:abcd';const { identifier, digest } = uriToStatementIdAndDigest(statementUri);console.log('Identifier:', identifier, 'Digest:', digest);Throws
If the statementUri does not follow the expected format.
Description
The function splits the statementUri string by the colon (:) delimiter and checks if it conforms to the expected format.
If the format is valid, it extracts the identifier and suffix (digest) parts. The digest is then prefixed with ‘0x’ to form
the correct statement digest. The function returns an object containing both the identifier and the formatted digest.
