Struct wasmi::RuntimeArgs

pub struct RuntimeArgs<'a>(_);

Wrapper around slice of RuntimeValue for using it as an argument list conveniently.

Implementations

impl<'a> RuntimeArgs<'a>

pub fn nth_checked<T>(&self, idx: usize) -> Result<T, Trap>where
    T: FromRuntimeValue,

Extract argument by index idx.

Errors

Returns Err if cast is invalid or not enough arguments.

pub fn nth_value_checked(&self, idx: usize) -> Result<RuntimeValue, Trap>

Extract argument as a RuntimeValue by index idx.

Errors

Returns Err if this list has not enough arguments.

pub fn nth<T>(&self, idx: usize) -> Twhere
    T: FromRuntimeValue,

Extract argument by index idx.

Panics

Panics if cast is invalid or not enough arguments.

pub fn len(&self) -> usize

Total number of arguments

Trait Implementations

impl<'a> AsRef<[RuntimeValue]> for RuntimeArgs<'a>

fn as_ref(&self) -> &[RuntimeValue]

impl<'a> Debug for RuntimeArgs<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a [RuntimeValue]> for RuntimeArgs<'a>

fn from(inner: &'a [RuntimeValue]) -> Self

Converts to this type from the input type.
