From a3f143c461444c0b56360bbf468615fa814a8372 Mon Sep 17 00:00:00 2001 From: Manas Date: Mon, 18 Nov 2024 20:06:58 +0530 Subject: [PATCH] rust: block: simplify Result<()> in validate_block_size return `Result` is used in place of `Result<()>` because the default type parameters are unit `()` and `Error` types, which are automatically inferred. Thus keep the usage consistent throughout codebase.
