Struct swim_structure::item::Attr

#[repr(C)]
pub struct Attr<'a> { /* fields omitted */ }

Field variant representing a key-value attribute with a Text key and a Value-typed value.

Examples

Construct a new Attr field:

let field = Attr::new(Text::from_str("a"), Value::from(true));

Methods

impl<'a> Attr<'a>

pub fn new(key: Text<'a>, val: Value<'a>) -> Attr<'a>

Returns a reference to this Attr's value.

pub fn get_val_mut(&mut self) -> &mut Value<'a>

Returns a mutable reference to this Attr's value.

pub fn get_key_val(&self) -> (&Text<'a>, &Value<'a>)

Returns a pair of references to this Attr's key and value.

pub fn get_key_val_mut(&mut self) -> (&Text<'a>, &mut Value<'a>)

Returns a pair of references to this Attr's key and mutable value.

pub fn as_field(&self) -> &Field<'a>

Upcasts this Attr reference to a Field reference.

pub fn as_mut_field(&mut self) -> &mut Field<'a>
