Enum concordium_std::test_infrastructure::ContractStateError

pub enum ContractStateError {
    Overflow,
    Write,
    Offset,
    Default,
}

An error that is raised when operating with Seek, Write, or Read trait methods of the ContractStateTest type.

Variants

Overflow

The computation of the new offset would result in an overflow.

Write

An error occurred when writing to the contract state.

Offset

The new offset would be out of bounds of the state.

Default

Some other error occurred.

Trait Implementations

impl Debug for ContractStateError

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

Formats the value using the given formatter.

impl Default for ContractStateError

fn default() -> Self

Returns the “default value” for a type.

impl From<TryFromIntError> for ContractStateError

fn from(_: TryFromIntError) -> Self

Performs the conversion.

impl<T: AsMut<Vec<u8>> + AsMut<[u8]> + AsRef<[u8]>> HasContractState<ContractStateError> for ContractStateTest<T>

type ContractStateData = T

fn open(data: Self::ContractStateData) -> Self

Open the contract state. Only one instance can be opened at the same time.

fn size(&self) -> u32

Get the current size of contract state.

fn truncate(&mut self, new_size: u32)

Truncate the state to the given size. If the given size is more than the current state size this operation does nothing. The new position is at most at the end of the stream.

fn reserve(&mut self, len: u32) -> bool

Make sure that the memory size is at least that many bytes in size. Returns true iff this was successful. The new bytes are initialized as 0.

impl PartialEq<ContractStateError> for ContractStateError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
