pub struct Printer { /* private fields */ }
Expand description
A printer for a regular expression abstract syntax tree.
A printer converts an abstract syntax tree (AST) to a regular expression
pattern string. This particular printer uses constant stack space and heap
space proportional to the size of the AST.
This printer will not necessarily preserve the original formatting of the
regular expression pattern string. For example, all whitespace and comments
are ignored.
Print the given Ast
to the given writer. The writer must implement
fmt::Write
. Typical implementations of fmt::Write
that can be used
here are a fmt::Formatter
(which is available in fmt::Display
implementations) or a &mut String
.
Formats the value using the given formatter.
