Struct holochain_wasmer_host::prelude::types::FuncSig

pub struct FuncSig { /* fields omitted */ }

The signature of a function that is either implemented in a wasm module or exposed to wasm by the host.

Implementations

impl FuncSig

pub fn new<Params, Returns>(params: Params, returns: Returns) -> FuncSig where
    Params: Into<Cow<'static, [Type]>>,
    Returns: Into<Cow<'static, [Type]>>, 

Creates a new function signatures with the given parameter and return types.

pub fn params(&self) -> &[Type]

Parameter types.

pub fn returns(&self) -> &[Type]

Return types.

pub fn check_param_value_types(&self, params: &[Value]) -> bool

Returns true if parameter types match the function signature.

Trait Implementations

impl Clone for FuncSig

pub fn clone(&self) -> FuncSig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FuncSig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FuncSig

pub fn deserialize<__D>(
    __deserializer: __D
) -> Result<FuncSig, <__D as Deserializer<'de>>::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for FuncSig

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

Formats the value using the given formatter.

impl Eq for FuncSig

impl From<Converter<Signature>> for FuncSig

pub fn from(signature: Converter<Signature>) -> FuncSig

Performs the conversion.

impl Hash for FuncSig

pub fn hash<__H>(&self, state: &mut __H) where
    __H: Hasher, 

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<FuncSig> for FuncSig

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Serialize for FuncSig

pub fn serialize<__S>(
    &self,
    __serializer: __S
) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
