Struct soroban_env_host::Object

pub struct Object(_);

Wrapper for a RawVal that is tagged with one of the object types, interpreting the RawVal’s body as containing a 32-bit object-code handle to a host object of the object-type.

impl FromValue for Object

fn from_value(val: Value) -> Option<Object>

Create a value of type Self from a given Value.

impl RawValConvertible for Object

fn is_val_type(v: RawVal) -> bool

Returns true if v is in a union state compatible with Self.

unsafe fn unchecked_from_val(v: RawVal) -> Object

Converts the bits making up a Val into Self without checking that the Val is tagged correctly, assuming that such a check has been performed elsewhere. It is the caller’s responsibility to arrange that such checks have occurred before calling unchecked_from_val, which is why it is marked as unsafe (it does not represent a risk of memory-unsafety, merely “serious logic errors”).

fn try_convert(v: RawVal) -> Option<Self>

Attempt a conversion from Val to Self, returning None if the provided Val is not tagged correctly. By default this calls Self::is_val_type and Self::unchecked_from_val, but it can be customized on a type-by-type basis to avoid redundant tag tests and produce more efficient code, as it is done for Static values like bool.
