Struct design_pattern_examples_rust::state::state_context::StateEscapedSingleQuotedText

struct StateEscapedSingleQuotedText {}

Represents being in an escaped character sequence inside a single-quoted string. We don’t do anything with the escaped character other than output it. Handling escaped characters allows us to more accurately detect the end of the string.

Transitions to the following states for the seen input:

• {ANY} - go to CurrentState::SingleQuotedText (end of escape sequence)

• StateChar::Eof - go to CurrentState::Done (no more input)
