Struct oasis_runtime_sdk::state::Options

pub struct Options {
    pub mode: Option<Mode>,
    pub tx: Option<TransactionWithMeta>,
    pub internal: Option<bool>,
    pub rng_local_entropy: bool,
}

Environment modification options.

Fields

mode: Option<Mode>

tx: Option<TransactionWithMeta>

internal: Option<bool>

rng_local_entropy: bool

Implementations

impl Options

pub fn new() -> Self

Create options with default values.

pub fn with_mode(self, mode: Mode) -> Self

Change the execution mode of the environment.

pub fn with_tx(self, tx: TransactionWithMeta) -> Self

Change the active transaction of the environment.

pub fn with_internal(self, internal: bool) -> Self

Change the internal flag of the environment.

pub fn with_rng_local_entropy(self) -> Self

Request for local entropy to be mixed into the current RNG.

Determinisim

Using this method will result in non-deterministic behavior as the node’s local entropy is mixed into the RNG. As such, this method should only be used in cases where non-determinism is not problematic (e.g. local queries).

Trait Implementations

impl Clone for Options

fn clone(&self) -> Options

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Options

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

Formats the value using the given formatter.

impl Default for Options

fn default() -> Options

Returns the “default value” for a type.
