Struct FuncSig 

pub struct FuncSig { /* private fields */ }

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 BorshDeserialize for FuncSig

fn deserialize_reader<__R>(reader: &mut __R) -> Result<FuncSig, Error>

where __R: Read,

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for FuncSig

fn serialize<__W>(&self, writer: &mut __W) -> Result<(), Error>

where __W: Write,

impl Clone for FuncSig

fn clone(&self) -> FuncSig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FuncSig

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

Formats the value using the given formatter.

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

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

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

Formats the value using the given formatter.

impl From<&FuncSig> for ExternDescriptor

fn from(other: &FuncSig) -> ExternDescriptor

Converts to this type from the input type.

impl From<FuncSig> for ExternDescriptor

fn from(other: FuncSig) -> ExternDescriptor

Converts to this type from the input type.

impl Hash for FuncSig

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FuncSig

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

impl Serialize for FuncSig

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.
