Implementations§
Source§impl<M: ManagedTypeApi> BigInt<M>
impl<M: ManagedTypeApi> BigInt<M>
Sourcepub unsafe fn new_uninit() -> Self
pub unsafe fn new_uninit() -> Self
Creates a new object, without initializing it.
§Safety
The value needs to be initialized after creation, otherwise the VM will halt the first time the value is attempted to be read.

pub fn from_biguint(sign: Sign, unsigned: BigUint<M>) -> Self
Sourcepub fn to_parts(self) -> (Sign, BigUint<M>)
pub fn to_parts(self) -> (Sign, BigUint<M>)
Convert this BigInt
into its Sign
and BigUint
magnitude,
the reverse of BigInt::from_biguint
.
Sourcepub unsafe fn into_big_uint_unchecked(self) -> BigUint<M>
pub unsafe fn into_big_uint_unchecked(self) -> BigUint<M>
Converts to an unsigned BigUint
, without performing any checks.
§Safety
If the number is negative, undefined behavior might occur further down the execution.
Sourcepub fn into_big_uint(self) -> ManagedOption<M, BigUint<M>>
pub fn into_big_uint(self) -> ManagedOption<M, BigUint<M>>
Converts this BigInt
into a BigUint
, if it’s not negative.

Source§fn transmute_from_handle_ref(handle_ref: &M::BigIntHandle) -> &Self
fn transmute_from_handle_ref(handle_ref: &M::BigIntHandle) -> &Self
Implement carefully, since the underlying transmutation is an unsafe operation.
For types that wrap a handle to some VM-managed data,
make sure the type only contains the handle (plus ZSTs if necessary).
For types that just wrap another managed type it is easier, call for the wrapped object.

Source§const SKIPS_RESERIALIZATION: bool = false
const SKIPS_RESERIALIZATION: bool = false
If true, then the encoding of the item is identical to the payload,
and no further conversion is necessary
(the underlying buffer can be used as-is during serialization).
False for all managed types, but true for basic types (like
u32
).Source§type PAYLOAD = ManagedVecItemPayloadBuffer<4>
