Function complete_parser 

pub fn complete_parser<Ctx, P: Parser<Ctx>>(
    input: &str,
    ctx: Ctx,
) -> BTreeSet<Cow<'static, str>>

Computes the completion suggestions for a value using an explicit parser

compute_parser takes an input as a string slice with a parsing context and returns a set of completion suggestions for the last token in the input, if any.

This function is similar to complete but is expects a parser as its second generic parameter. It is intended to be used with custom parsers or for types that don’t implement Parsable.

Examples

use cmdparse::complete_parser;
use cmdparse::parsers::BooleanParser;
use std::collections::BTreeSet;

let suggestions = complete_parser::<_, BooleanParser>("tr", ());
assert_eq!(suggestions, BTreeSet::from(["ue".into()]));
