Implementations

impl ParamInfo

pub const fn required(name: Atom, type_id: TypeId) -> Self

Create a required parameter.

pub const fn optional(name: Atom, type_id: TypeId) -> Self

Create an optional parameter.

pub const fn rest(name: Atom, type_id: TypeId) -> Self

Create a rest parameter.

pub const fn unnamed(type_id: TypeId) -> Self

Create an unnamed required parameter.

Trait Implementations

impl Clone for ParamInfo

fn clone(&self) -> ParamInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamInfo

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

Formats the value using the given formatter.

impl Default for ParamInfo

fn default() -> ParamInfo

Returns the “default value” for a type.

impl Hash for ParamInfo

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

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 PartialEq for ParamInfo

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