|
|||
|
|
<p>The nesting limit controls how deep the abstract syntax tree is allowed
|
|||
|
|
to be. If the AST exceeds the given limit (e.g., with too many nested
|
|||
|
|
groups), then an error is returned by the parser.</p>
|
|||
|
|
<p>The purpose of this limit is to act as a heuristic to prevent stack
|
|||
|
|
overflow for consumers that do structural induction on an <code>Ast</code> using
|
|||
|
|
explicit recursion. While this crate never does this (instead using
|
|||
|
|
constant stack space and moving the call stack to the heap), other
|
|||
|
|
crates may.</p>
|
|||
|
|
<p>This limit is not checked until the entire Ast is parsed. Therefore,
|
|||
|
|
if callers want to put a limit on the amount of heap space used, then
|
|||
|
|
they should impose a limit on the length, in bytes, of the concrete
|
|||
|
|
pattern string. In particular, this is viable since this parser
|
|||
|
|
implementation will limit itself to heap space proportional to the
|
|||
|
|
length of the pattern string.</p>
|
|||
|
|
<p>Note that a nest limit of <code>0</code> will return a nest limit error for most
|
|||
|
|
patterns but not all. For example, a nest limit of <code>0</code> permits <code>a</code> but
|
|||
|
|
not <code>ab</code>, since <code>ab</code> requires a concatenation, which results in a nest
|
|||
|
|
depth of <code>1</code>. In general, a nest limit is not something that manifests
|
|||
|
|
in an obvious way in the concrete syntax, therefore, it should not be
|
|||
|
|
used in a granular way.</p>

|
|||
|
|
<p>Octal syntax is a little-known way of uttering Unicode codepoints in
|
|||
|
|
a regular expression. For example, <code>a</code>, <code>\x61</code>, <code>\u0061</code> and
|
|||
|
|
<code>\141</code> are all equivalent regular expressions, where the last example
|
|||
|
|
shows octal syntax.</p>
|
|||
|
|
<p>While supporting octal syntax isn’t in and of itself a problem, it does
|
|||
|
|
make good error messages harder. That is, in PCRE based regex engines,
|
|||
|
|
syntax like <code>\0</code> invokes a backreference, which is explicitly
|
|||
|
|
unsupported in Rust’s regex engine. However, many users expect it to
|
|||
|
|
be supported. Therefore, when octal support is disabled, the error
|
|||
|
|
message will explicitly mention that backreferences aren’t supported.</p>
|
|||
|
|
<p>Octal syntax is disabled by default.</p>
