Struct FnDecl 

pub struct FnDecl {
    pub addr: Option<u64>,
    pub name: String,
    pub attrs: Vec<Attribute>,
    pub signature: Option<Signature>,
    pub locals: Vec<LocalDecl>,
    pub body: Vec<Stmt>,
}

A function declaration.

signature carries typed parameters and return type when known (e.g. recovered from DWARF). When absent, the function emits as fn name() { … } and behaves as untyped.

Fields

addr: Option<u64>

Optional @addr(0x…) directive preceding fn. Required for functions whose name doesn’t encode the address (i.e. anything not matching sub_<hex>); the decompiler emits it always for clarity.

name: String

attrs: Vec<Attribute>

#[…] attributes attached to the fn keyword. Carry per- function profile info (abi, cc, saves, …); module-level defaults in the @module header can shadow these.

signature: Option<Signature>

Typed parameters and return type, when known.

locals: Vec<LocalDecl>

Variable / register declarations at the top of the function body. Stack slots discovered from [ebp±N] accesses get a Stack decl; registers the function touches get a Register decl. Purely informational today (the prologue’s pinned bytes already encode the actual stack allocation); future work can use the size hints to drive lowering of a re-allocated frame.

body: Vec<Stmt>

Trait Implementations

impl Clone for FnDecl

fn clone(&self) -> FnDecl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FnDecl

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

Formats the value using the given formatter.

impl PartialEq for FnDecl

fn eq(&self, other: &FnDecl) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
