Function xpct::match_fields

pub fn match_fields<'a, T>(spec: FieldsSpec<'a, T>) -> Matcher<'a, T, ()>where
    T: 'a,

Succeeds when all the fields of a struct succeed.

This matcher operates on a struct and allows for matching on each field separately. This is used with the fields! macro.

This succeeds when each field of the struct succeeds, and skipping/omitting fields does not make it fail.

This matcher can be used for both regular structs and tuple structs. See fields! for details.

Examples

use xpct::{be_gt, be_some, be_true, expect, fields, have_prefix, match_fields};

struct Person {
    id: String,
    name: Option<String>,
    age: u32,
    is_superstar: bool,
}

let value = Person {
    id: String::from("REV12-62-05-JAM41"),
    name: Some(String::from("Raphaël")),
    age: 44,
    is_superstar: true,
};

expect!(value).to(match_fields(fields!(Person {
    id: have_prefix("REV"),
    name: be_some(),
    age: be_gt(0),
    is_superstar: be_true(),
})));
