Struct zvariant::Array

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

A helper type to wrap arrays in a Value.

API is provided to convert from, and to a Vec.

Implementations

impl<'a> Array<'a>

pub fn new(element_signature: Signature<'_>) -> Array<'_>

Create a new empty Array, given the signature of the elements.

pub fn append<'e: 'a>(&mut self, element: Value<'e>) -> Result<()>

Append element.

Errors

if element’s signature doesn’t match the element signature self was created for.

pub fn get(&self) -> &[Value<'a>]

Get all the elements.

pub fn len(&self) -> usize

Get the number of elements.

pub fn is_empty(&self) -> bool

pub fn signature(&self) -> Signature<'static>

Get the signature of this Array.

NB: This method potentially allocates and copies. Use full_signature if you’d like to avoid that.

pub fn full_signature(&self) -> &Signature<'_>

Get the signature of this Array.

pub fn element_signature(&self) -> &Signature<'_>

Get the signature of the elements in the Array.
