Struct Loc

pub struct Loc<T>(pub T, pub Location);

Represents a T with a Location.

This is commonly used to represent bits of a parse tree, remembering where they came from in the source code.

Tuple Fields

0: T

1: Location

Implementations

impl<T> Loc<T>

pub fn as_ref(&self) -> Loc<&T>

Convert an &Loc<T> to a Loc<&T>.

Trait Implementations

impl AST for Loc<u64>

type Generous = Loc<String>

The parser type that turns into Self.

fn validate( report: &mut impl FnMut(Location, &str), value: &Self::Generous, ) -> Result<Self, Invalid>

Attempt to construct a Self given its parse tree.

impl<T: Clone> Clone for Loc<T>

fn clone(&self) -> Loc<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Loc<T>

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

Formats the value using the given formatter.

impl<U, T: PartialEq<U>> PartialEq<U> for Loc<T>

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