Issue #13626 has been updated by ioquatix (Samuel Williams). > Fwiw, I'm also not convinced String#<< behavior about changing > write_buffer to Encoding::UTF-8 in your above example is good > behavior on Ruby's part... Agreed. ---------------------------------------- Feature #13626: Add String#byteslice! https://bugs.ruby-lang.org/issues/13626#change-65362 * Author: ioquatix (Samuel Williams) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- It's a common pattern in IO buffering, to read a part of a string while leaving the remainder. ~~~ # Consume only part of the read buffer: result = @read_buffer.byteslice(0, size) @read_buffer = @read_buffer.byteslice(size, @read_buffer.bytesize) ~~~ It would be nice if this code could be simplified to: ~~~ result = @read_buffer.byteslice!(size) ~~~ Additionally, this allows a significantly improved implementation by the interpreter. -- https://bugs.ruby-lang.org/ Unsubscribe:
