Struct docopt::Deserializer[][src]

pub struct Deserializer<'de> { /* fields omitted */ }
Expand description

Deserializer for ArgvMap into your own Deserializeable types.

In general, you shouldn’t have to use this type directly. It is exposed in case you want to write a generic function that produces a deserializable value. For example, here’s a function that takes a usage string, an argv and produces a deserializable value:

extern crate serde;
use docopt::Docopt;
use serde::de::Deserialize;

fn deserialize<'de, D: Deserialize<'de>>(usage: &str, argv: &[&str])
                        -> Result<D, docopt::Error> {
    Docopt::new(usage)
           .and_then(|d| d.argv(argv.iter()).deserialize())
}
