Estimates the (deep) size of this object in bytes (including heap owned inner data)

fn estimate_mem_units(&self) -> usize

Estimates the number of units this object holds in memory where the unit byte size is usually a constant known to the caller as well (and hence we avoid computing it over and over)

impl OptionFromWasmAbi for Hash

fn is_none(abi: &<Hash as FromWasmAbi>::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 Ord for Hash

impl PartialEq for Hash

We only override PartialEq because clippy wants us to. This should always hold: PartialEq(x,y) => Hash(x) == Hash(y)

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

Tests greater than (for self and other) and is used by the > operator.

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<Hash>

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.

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

type Error = Error

fn try_cast_from<'a, R>( value: &'a R, ) -> Result<Cast<'a, Hash>, <Hash as TryCastFromJs>::Error>

where R: AsRef<JsValue> + 'a,

Try to cast a JsValue into a Rust object. This should be user-defined function that attempts to cast a JsValue into a Rust object or interpret a source data and create a temporary struct owned by by the Cast.

fn try_owned_from(value: impl AsRef<JsValue>) -> Result<Self, Self::Error>

Perform a user cast and consume the Cast container. This function will return a temporary user-created object created during [try_cast_from] or a clone of the casted reference.

fn resolve_cast<'a, R>( js: &'a R, create: impl FnOnce() -> Result<Cast<'a, Self>, Self::Error>, ) -> Result<Cast<'a, Self>, Self::Error>

where R: AsRef<JsValue> + 'a,

Try to cast a JsValue into a Rust object, in cast of failure invoke a user-supplied closure that can try to create an instance of the object based on the supplied JsValue. Unlike the [resolve] function, this function expects create closure to return a Cast. This is useful when routing the creation of the object to another function that is capable of creating a compatible Cast wrapper.

impl TryFrom<&[u8]> for Hash
