Source

pub fn actual_type(&self) -> &TypeDefinition

Source

pub fn has_default_type(&self) -> bool

Returns true if the current Value’s actual type is the same as its default type E.g. if the type is integer for an Integer value, or integer/u8 for a typed integer value This will return false for an integer value if the actual type is one of the following:

  • an ImplType<integer, x>
  • a new nominal type containing an integer TODO #604: this does not match all cases of default types from the point of view of the compiler - integer variants (despite bigint) can be distinguished based on the instruction code, but for text variants, the variant must be included in the compiler output - so we need to handle theses cases as well. Generally speaking, all variants except the few integer variants should never be considered default types.
Source

pub fn try_get_property<'a>( &self, key: impl Into<ValueKey<'a>>, ) -> Result<ValueContainer, AccessError>

Gets a property on the value if applicable (e.g. for map and structs)

Source

pub fn try_set_property<'a>( &mut self, key: impl Into<ValueKey<'a>>, val: ValueContainer, ) -> Result<(), AccessError>

Sets a property on the value if applicable (e.g. for maps)

Methods from Deref<Target = CoreValue>§

Source

pub fn is_collection_value(&self) -> bool

Check if the CoreValue is a combined value type (List, Map) that contains inner ValueContainers.

Source

pub fn default_type_definition(&self) -> TypeDefinition

Get the default type of the CoreValue type definition. This method uses the CoreLibPointerId to retrieve the corresponding type reference from the core library. For example, a CoreValue::TypedInteger(i32) will return the type ref integer/i32
