Struct Sig 

pub struct Sig {
    pub returns: Option<usize>,
    pub params: Vec<Param>,
    pub variadic: bool,
    pub prototyped: bool,
}

What a function takes and gives back.

Fields

returns: Option<usize>

Which of the unit’s types it returns, and None for void.

params: Vec<Param>

The parameters in order.

variadic: bool

Whether it ends in ....

prototyped: bool

Whether the program wrote a parameter list rather than leaving it empty.

DW_AT_prototyped, and it is not the same question as whether the list is empty: int f() says nothing about what f takes and int f(void) says it takes nothing, and a debugger that could not tell them apart would offer to call the first with no arguments.

Trait Implementations

impl Clone for Sig

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sig

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

Formats the value using the given formatter.

impl Default for Sig

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Sig

impl PartialEq for Sig

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