Macro blob 

blob!() { /* proc-macro */ }

Converts a hex string to a compile-time [Blob<N>].

Two forms:

• blob!("DEADBEEF") — exact-fit Blob<4> where N equals the decoded byte count.
• blob!("DEADBEEF", 128) — Blob<128> zero-padded to the given capacity; the decoded byte count must not exceed the capacity.

In both forms len is set to the decoded byte count. The hex string must have an even number of characters.

Example

use xrpl_common_stdlib::blob;
use xrpl_common_stdlib::types::blob::Blob;

const EXACT: Blob<4> = blob!("DEADBEEF");
const PADDED: Blob<32> = blob!("DEADBEEF", 32);
