Struct arithmetic_parser::FnDefinition

#[non_exhaustive]
pub struct FnDefinition<'a, T: Grammar> {
    pub args: Spanned<'a, Destructure<'a, T::Type<'a>>>,
    pub body: Block<'a, T>,
}

Function definition, e.g., |x, y| x + y.

A function definition consists of a list of arguments and the function body.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

args: Spanned<'a, Destructure<'a, T::Type<'a>>>

Function arguments, e.g., x, y.

body: Block<'a, T>

Function body, e.g., x + y.

Trait Implementations

impl<'a, T: Grammar> Clone for FnDefinition<'a, T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug + Grammar> Debug for FnDefinition<'a, T>

where T::Type<'a>: Debug,

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

Formats the value using the given formatter.

impl<'a, T> PartialEq for FnDefinition<'a, T>

where T: Grammar, T::Lit: PartialEq, T::Type<'a>: PartialEq,

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

This method tests for self and other values to be equal, and is used by ==.

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

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