Implementations

impl<'a> ValueRef<'a>

pub fn to_owned(&self) -> Value

Converts the current non-owning value to an owned Value.

This is achieved by deep copying all underlying structures and borrowed buffers.

Panics

Panics in unable to allocate memory to keep all internal structures and buffers.

Examples

use rmpv::{Value, ValueRef};

let val = ValueRef::Array(vec![
   ValueRef::Nil,
   ValueRef::from(42),
   ValueRef::Array(vec![
       ValueRef::from("le message"),
   ])
]);

let expected = Value::Array(vec![
    Value::Nil,
    Value::from(42),
    Value::Array(vec![
        Value::String("le message".into())
    ])
]);

assert_eq!(expected, val.to_owned());

pub fn index(&self, index: usize) -> &ValueRef<'_>

pub fn as_u64(&self) -> Option<u64>

If the ValueRef is an integer, return or cast it to a u64. Returns None otherwise.

Examples

use rmpv::ValueRef;

assert_eq!(Some(42), ValueRef::from(42).as_u64());

pub fn as_array(&self) -> Option<&Vec<ValueRef<'_>>>

If the ValueRef is an Array, returns the associated vector. Returns None otherwise.

Examples

use rmpv::ValueRef;

let val = ValueRef::Array(vec![ValueRef::Nil, ValueRef::Boolean(true)]);

assert_eq!(Some(&vec![ValueRef::Nil, ValueRef::Boolean(true)]), val.as_array());
