[−][src]Struct wasmer_runtime::Function

pub struct Function<'a> { /* fields omitted */ }

A representation of an exported WebAssembly function.

Methods

impl<'a> Function<'a>
[src]

pub fn call(&mut self, params: &[Value]) -> Result<Vec<Value>, Box<CallError>>
[src]

Call an exported webassembly function safely.

Pass arguments by wrapping each one in the Value enum. The returned values are also each wrapped in a Value.

Note:

This returns CallResult<Vec<Value>> in order to support the future multi-value returns webassembly feature.

Usage:

instance
    .func("foo")?
    .call(&[])?;

pub fn signature(&self) -> &FuncSig
