Struct wasmi_validation::util::Locals

pub struct Locals<'a> { /* private fields */ }

Locals are the concatenation of a slice of function parameters with function declared local variables.

Local variables are given in the form of groups represented by pairs of a value_type and a count.

Implementations

impl<'a> Locals<'a>

pub fn new(
    params: &'a [ValueType],
    local_groups: &'a [Local]
) -> Result<Locals<'a>, Error>

Create a new wrapper around declared variables and parameters.

pub fn param_count(&self) -> u32

Returns parameter count.

pub fn count(&self) -> u32

Returns total count of all declared locals and paramaterers.

pub fn type_of_local(&self, idx: u32) -> Result<ValueType, Error>

Returns the type of a local variable (either a declared local or a param).

Returns Err in the case of overflow or when idx falls out of range.

impl<'a> Debug for Locals<'a>

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

Formats the value using the given formatter.
