Struct RirFunctionView 

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

A view into a function’s instructions within the RIR.

This provides a way to iterate over just the instructions belonging to a specific function, enabling per-function analysis without copying data.

Implementations

impl<'a> RirFunctionView<'a>

pub fn get(&self, inst_ref: InstRef) -> &'a Inst

Get the instruction at the given reference.

Note: The reference must be within this function’s range.

pub fn fn_decl(&self) -> &'a Inst

Get the FnDecl instruction for this function.

pub fn iter(&self) -> impl Iterator<Item = (InstRef, &'a Inst)>

Iterate over all instructions in this function (including FnDecl).

pub fn len(&self) -> usize

Get the number of instructions in this function view.

pub fn is_empty(&self) -> bool

Whether this view is empty (should never be true for valid functions).

pub fn rir(&self) -> &'a Rir

Access the underlying RIR for operations that need the full context (e.g., accessing extra data).

Trait Implementations

impl<'a> Debug for RirFunctionView<'a>

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

Formats the value using the given formatter.
