class String::Builder
Overview
Similar to IO::Memory
, but optimized for building a single string.
You should never have to deal with this class. Instead, use String.build
.
Defined in:
string/builder.crConstructors

Moves the write pointer, and the resulting string bytesize, by the given amount.
Chomps the last byte from the string buffer.
If the byte is '\n'
and there's a '\r'
before it, it is also removed.
