Struct AttributeMut

pub struct AttributeMut<'a> { /* private fields */ }

Allows mutable access to the value and surrounding Decor of an Attribute but not to its key.

This type wraps the attribute returned by Body::get_attribute_mut and in the iterator returned by Body::attributes_mut.

Implementations

impl<'a> AttributeMut<'a>

pub fn get(&self) -> &Attribute

Returns an immutable reference to the wrapped Attribute.

pub fn key_decor_mut(&mut self) -> &mut Decor

Returns a mutable reference to the wrapped Attribute’s key’s decor.

pub fn value_mut(&mut self) -> &mut Expression

Returns a mutable reference to the wrapped Attribute’s value.

Methods from Deref<Target = Attribute>

pub fn has_key(&self, key: &str) -> bool

Returns true if the attribute has the given key.

Example

use hcl_edit::{structure::Attribute, Ident};

let attr = Attribute::new(Ident::new("foo"), "bar");
assert!(attr.has_key("foo"));
assert!(!attr.has_key("bar"));

Trait Implementations

impl<'a> Decorate for AttributeMut<'a>

fn decor(&self) -> &Decor

Returns a reference to the object’s Decor.

fn decor_mut(&mut self) -> &mut Decor

Returns a mutable reference to the object’s Decor.

fn decorate(&mut self, decor: impl Into<Decor>)

Decorate the object with decor in-place.

fn decorated(self, decor: impl Into<Decor>) -> Self

where Self: Sized,

Decorate the object with decor and return the modified value.

impl<'a> Deref for AttributeMut<'a>

type Target = Attribute

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a> Span for AttributeMut<'a>

fn span(&self) -> Option<Range<usize>>

Obtains the span information. This only returns Some if the value was emitted by the parser.
