class Gem::YAMLSerializer::Parser

Constants

MAPPING_KEY_RE

A plain (unquoted) mapping key followed by “:”. “#” inside a key is literal unless preceded by a space (which would start a comment).

MAX_NESTING_DEPTH
QUOTED_KEY_RE

A quoted mapping key followed by “:”. A whole-line quoted scalar cannot match because its closing quote is at the end of the line.
