Struct scryptenc_wasm::Params

pub struct Params(/* private fields */);

The scrypt parameters used for the encrypted data.

Implementations

impl Params

pub fn new(ciphertext: &[u8]) -> Result<Params, JsError>

Creates a new instance of the scrypt parameters from ciphertext.

Errors

Returns Err if any of the following are true:

• ciphertext is shorter than 128 bytes.
• The magic number is invalid.
• The version number is the unrecognized scrypt version number.
• The scrypt parameters are invalid.

pub fn log_n(&self) -> u8

Gets log2 of the scrypt parameter N.

pub fn n(&self) -> u64

Gets N parameter.

pub fn r(&self) -> u32

Gets r parameter.

pub fn p(&self) -> u32

Gets p parameter.

Trait Implementations

impl Clone for Params

fn clone(&self) -> Params

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Params

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

Formats the value using the given formatter.

impl From<Params> for JsValue

fn from(value: Params) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Params

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 Params

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 LongRefFromWasmAbi for Params

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = Ref<'static, Params>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for Params

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 Params

fn none() -> Self::Abi

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

impl RefFromWasmAbi for Params

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, Params>

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 Params

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, Params>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for Params

type Error = JsValue

The type returned in the event of a conversion error.

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

Performs the conversion.

impl VectorFromWasmAbi for Params

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[Params]>

impl VectorIntoWasmAbi for Params

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

fn vector_into_abi(vector: Box<[Params]>) -> Self::Abi

impl WasmDescribe for Params

fn describe()

impl WasmDescribeVector for Params

fn describe_vector()

impl Copy for Params
