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

fn from_wire(wire: Self::Wire) -> Result<Self, WireError>

Recovers the Rust value from the wire value.

impl FromWasmAbi for SdkRandomNumberClient

type Abi = WasmPtr<WasmRefCell<SdkRandomNumberClient>>

unsafe fn from_abi(js: Self::Abi) -> Self

Recover a Self from Self::Abi.

type Abi = WasmPtr<WasmRefCell<SdkRandomNumberClient>>

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

fn into_abi(self) -> Self::Abi

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 = WasmPtr<WasmRefCell<SdkRandomNumberClient>>

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>

impl NullableFromWasmAbi for SdkRandomNumberClient

fn is_null(abi: &Self::MaybeAbi) -> bool

Tests the ABI value for Nullable::Null.

impl NullableIntoWasmAbi for SdkRandomNumberClient

fn null() -> Self::MaybeAbi

Returns the ABI value for Nullable::Null, which JS reads as null.

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 = WasmPtr<WasmRefCell<SdkRandomNumberClient>>

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.

Same as RefFromWasmAbi::ref_from_abi

impl SupportsConstructor for SdkRandomNumberClient

impl SupportsInstanceProperty for SdkRandomNumberClient

impl SupportsStaticProperty for SdkRandomNumberClient

impl ToWasm for SdkRandomNumberClient

Available on crate feature wasm only.

type Wire = SdkRandomNumberClient

The type JavaScript actually receives.

fn to_wire(self) -> Result<Self::Wire, WireError>

Converts the Rust value into the wire value.

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.

const NULLABLE: bool = false

Whether Self accepts null as a distinct value space, as Nullable<T> does. An enclosing Option then passes null through instead of reading it as None, so Option<T> is itself nullable exactly when T is not. JsValue does not set this: it accepts null as one value among all of them, not as a distinct space, and Option<JsValue> reads it as None like the ABI does. This is the JS-value side of NullableFromWasmAbi, which claims null at the ABI.
