Implementations

impl FnArgs

pub(crate) fn from_arg_spec(spec: i64) -> Result<Self>

pub(crate) fn into_arg_spec(self) -> u64

Trait Implementations

impl Clone for FnArgs

fn clone(&self) -> FnArgs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for FnArgs

fn default() -> FnArgs

Returns the “default value” for a type.

impl PartialEq for FnArgs

fn eq(&self, other: &FnArgs) -> 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.

impl Debug for FnArgs

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

Formats the value using the given formatter.

impl Copy for FnArgs

impl Eq for FnArgs

impl StructuralPartialEq for FnArgs
