A reflected HashMap

Required Methods

fn get_value<'a>(&'a self, key: &str) -> Option<Value<'a, 's>>

where 's: 'a,

fn is_empty(&self) -> bool

fn len(&self) -> usize

fn boxed_clone(&self) -> Box<dyn HashMapInstance<'s> + 's>

Returns a clone of the instance in a Box.

fn update<'a>( &'a mut self, update: &'a (dyn HashMapInstance<'s> + 's), field_mask: Option<&FieldMask>, replace_repeated: bool, ) -> Result<(), Error>

Updates an instance based on the instance passed in. If a field mask is specified only the fields passed with the mask will be updated.

fn values<'a>(&'a self) -> HashMap<String, CowValue<'a, 's>>

where 's: 'a,

Returns a HashMap containing all the attributes of the instance.

fn hashmap_eq(&self, inst: &(dyn HashMapInstance<'s> + 's)) -> bool

fn into_boxed_instance(self: Box<Self>) -> Box<dyn Instance<'s> + 's>

Provided Methods

fn contains(&self, sub_inst: &(dyn HashMapInstance<'s> + 's)) -> bool

Trait Implementations

impl<'s> Clone for Box<dyn HashMapInstance<'s> + 's>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'s> Debug for dyn HashMapInstance<'s> + 's

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'s> PartialEq for dyn HashMapInstance<'s> + 's

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl<'s, T> HashMapInstance<'s> for HashMap<String, T>

where T: Typed<'s> + Clone + 's + PartialEq,

fn get_value<'a>(&'a self, key: &str) -> Option<Value<'a, 's>>

where 's: 'a,

fn update<'a>( &'a mut self, update: &'a (dyn HashMapInstance<'s> + 's), field_mask: Option<&FieldMask>, replace_repeated: bool, ) -> Result<(), Error>

fn values<'a>(&'a self) -> HashMap<String, CowValue<'a, 's>>

where 's: 'a,

fn boxed_clone(&self) -> Box<dyn HashMapInstance<'s> + 's>

fn is_empty(&self) -> bool

fn len(&self) -> usize

fn hashmap_eq(&self, inst: &(dyn HashMapInstance<'s> + 's)) -> bool

fn contains(&self, sub_inst: &(dyn HashMapInstance<'s> + 's)) -> bool

fn into_boxed_instance(self: Box<Self>) -> Box<dyn Instance<'s> + 's>
