Struct SdkRandomNumberClient 

pub struct SdkRandomNumberClient;

Client exposing random-number generation to cross-platform bindings.

Implementations

impl SdkRandomNumberClient

pub fn new() -> Self

Construct a new client.

pub fn gen_bytes(&self, len: u32) -> Result<Vec<u8>, GenBytesError>

Generate len cryptographically-secure random bytes.

Returns GenBytesError::TooManyBytes if len exceeds 1 KiB. If you want over 1KiB of randomness, please reconsider your design.

pub fn gen_uuid(&self) -> String

Generate a random v4 UUID, sampled from a CRNG

This has 122 random bits of entropy.

pub fn gen_range(&self, min: u32, max: u32) -> Result<u32, GenRangeError>

Generate a cryptographically-secure random number in the range [min, max] (inclusive).

Returns GenRangeError::InvalidRange if min > max.

Trait Implementations

impl Default for SdkRandomNumberClient

fn default() -> SdkRandomNumberClient

Returns the “default value” for a type.

impl From<SdkRandomNumberClient> for JsValue

fn from(value: SdkRandomNumberClient) -> Self

Converts to this type from the input type.

impl FromWasmAbi for SdkRandomNumberClient

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for SdkRandomNumberClient

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl<UT> LiftRef<UT> for SdkRandomNumberClient

type LiftType = Arc<SdkRandomNumberClient>

impl LongRefFromWasmAbi for SdkRandomNumberClient

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<SdkRandomNumberClient>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl<UT> LowerError<UT> for SdkRandomNumberClient

fn lower_error(obj: Self) -> RustBuffer

Lower this value for scaffolding function return

impl<UT> LowerReturn<UT> for SdkRandomNumberClient

type ReturnType = <Arc<SdkRandomNumberClient> as LowerReturn<UniFfiTag>>::ReturnType

The type that should be returned by scaffolding functions for this type.

fn lower_return(obj: Self) -> Result<Self::ReturnType, RustCallError>

Lower the return value from an scaffolding call

fn handle_failed_lift( error: LiftArgsError, ) -> Result<Self::ReturnType, RustCallError>

Lower the return value for failed argument lifts

impl OptionFromWasmAbi for SdkRandomNumberClient

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for SdkRandomNumberClient

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for SdkRandomNumberClient

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<SdkRandomNumberClient>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for SdkRandomNumberClient

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<SdkRandomNumberClient>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for SdkRandomNumberClient

fn try_from_js_value(value: JsValue) -> Result<Self, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<Self>

Performs the conversion.
