Enum FnArg 

pub enum FnArg {
    Receiver(Receiver),
    Typed(PatType),
}

Available on crate feature full only.

An argument in a function signature: the n: usize in fn f(n: usize).

Variants

Receiver(Receiver)

Trait Implementations

impl Clone for FnArg

Available on crate feature clone-impls only.

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 FnArg

Available on crate feature extra-traits only.

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

Formats the value using the given formatter.

impl From<PatType> for FnArg

fn from(e: PatType) -> FnArg

Converts to this type from the input type.

impl From<Receiver> for FnArg

fn from(e: Receiver) -> FnArg

Converts to this type from the input type.

impl Hash for FnArg

Available on crate feature extra-traits only.

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Parse for FnArg

Available on crate feature parsing only.

fn parse(input: ParseStream<'_>) -> Result<Self>

impl PartialEq for FnArg

Available on crate feature extra-traits only.

fn eq(&self, other: &Self) -> 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 ToTokens for FnArg

Available on crate feature printing only.

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.

impl Eq for FnArg

Available on crate feature extra-traits only.
