Struct valuable::NamedValues[−][src]

pub struct NamedValues<'a> { /* fields omitted */ }

Expand description

Set of values from a Structable or Enumerable with named fields.

Implementations

[src]

impl<'a> NamedValues<'a>

[src]

pub fn new(
fields: &'a [NamedField<'a>],
values: &'a [Value<'a>]
) -> NamedValues<'a>

Create a new NamedValues instance.

Both fields and values must be the same length.

Panics

The method panics if fields and values are different lengths.

Examples

use valuable::{NamedField, NamedValues, Value};

let fields = [
    NamedField::new("foo"),
    NamedField::new("bar")
];
let values = [
    Value::U32(123),
    Value::U32(456),
];

let named_values = NamedValues::new(&fields, &values);

assert_eq!(
    named_values.get(&fields[0]).unwrap().as_u32(),
    Some(123));

[src]

pub fn get(&self, field: &NamedField<'_>) -> Option<&Value<'_>>

Get a value using a NamedField reference.

Examples

use valuable::{NamedField, NamedValues, Value};

let fields = [
    NamedField::new("foo"),
    NamedField::new("bar")
];
let values = [
    Value::U32(123),
    Value::U32(456),
];

let named_values = NamedValues::new(&fields, &values);

assert_eq!(
    named_values.get(&fields[0]).unwrap().as_u32(),
    Some(123));

[src]

pub fn get_by_name(&self, name: impl AsRef<str>) -> Option<&Value<'_>>

Get a value using string.

Examples

use valuable::{NamedField, NamedValues, Value};

let fields = [
    NamedField::new("foo"),
    NamedField::new("bar")
];
let values = [
    Value::U32(123),
    Value::U32(456),
];

let named_values = NamedValues::new(&fields, &values);

assert_eq!(
    named_values.get_by_name("foo").unwrap().as_u32(),
    Some(123));

[src]

pub fn iter<'b>(&'b self) -> Iter<'a, 'b>

Iterate all name-value pairs.

Examples

use valuable::{NamedField, NamedValues, Value};

let fields = [
    NamedField::new("foo"),
    NamedField::new("bar")
];
let values = [
    Value::U32(123),
    Value::U32(456),
];

let named_values = NamedValues::new(&fields, &values);

for (field, value) in named_values.iter() {
    println!("{:?}: {:?}", field, value);
}
