Function promql::parse

pub fn parse(e: &[u8]) -> Result<Node, Err<CompleteByteSlice>>

Parse expression string into an AST.

This parser operates on byte sequence instead of &str because of the fact that PromQL, like Go, allows raw byte sequences to be included in the string literals (e.g. {omg='∞'} is equivalent to both {omg='\u221e'} and {omg='\xe2\x88\x9e'}).
