Struct Separator 

pub struct Separator(/* private fields */);

The separator of a sep(separator, P) call — non-empty by construction.

An empty separator is not a parser that matches nothing: it is a cursor that never advances. walk_sep in praxis-runtime asks region[pos..].starts_with(sep_bytes), which is unconditionally true for an empty needle, so pos += sep_bytes.len() is pos += 0 and the loop pushes a freshly allocated value forever — an infinite loop that also grows the heap without bound.

A validate check would have caught the value only where someone remembered to call it; the type catches it at every construction site there will ever be, which is the house maxim (AGENTS.md: make illegal states unrepresentable).

Implementations

impl Separator

pub fn new(text: &str) -> Result<Self, EmptySeparator>

The only constructor. Refuses the empty string.

Errors

EmptySeparator when text is empty.

pub fn as_str(&self) -> &str

The separator text. Never empty.
