Struct Body

pub struct Body<'a> {
    pub locals: Vec<(u32, DataType)>,
    pub num_locals: u32,
    pub instructions: Vec<Instruction<'a>>,
    pub num_instructions: usize,
    pub name: Option<String>,
}

Body of a function in a wasm module

Fields

locals: Vec<(u32, DataType)>

Local variables of the function, given as tuples of (# of locals, type). Note that these do not include the function parameters which are given indices before the locals. So if a function has 2 parameters and a local defined here then local indices 0 and 1 will refer to the parameters and index 2 will refer to the local here.

num_locals: u32

instructions: Vec<Instruction<'a>>

num_instructions: usize

name: Option<String>

Implementations

impl<'a, 'b> Body<'a>

where 'b: 'a,

pub fn push_op(&mut self, op: Operator<'b>)

Push a new operator (instruction) to the end of the body

pub fn get_op(&self, idx: usize) -> &Operator<'_>

Get some operator (instruction) at the specified index of the body

pub fn get_instr_flag(&self, idx: usize) -> &InstrumentationFlag<'_>

Get the instrumentation of some operator in the body

pub fn clear_instr(&mut self, idx: usize, mode: InstrumentationMode)

Get the instrumentation of some operator in the body

pub fn end(&mut self)

Push an end operator (instruction) to the end of the body

Trait Implementations

impl<'a> Clone for Body<'a>

fn clone(&self) -> Body<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Body<'a>

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

Formats the value using the given formatter.

impl<'a> Default for Body<'a>

fn default() -> Body<'a>

Returns the “default value” for a type.
