Struct Node 

pub struct Node<'e> {
    pub kind: NodeKind<'e>,
    pub span: Span,
    pub leading_discards: Vec<Discard<'e>>,
}

Concrete EDN syntax tree.

Parse one with parse, then convert it to an Edn with Edn::try_from.

Fields

kind: NodeKind<'e>

span: Span

leading_discards: Vec<Discard<'e>>

Implementations

impl<'e> Node<'e>

pub const fn no_discards(kind: NodeKind<'e>, span: Span) -> Self

Construct a Node with the given kind and span and no leading discards.

pub const fn span(&self) -> Span

Trait Implementations

impl<'e> Clone for Node<'e>

fn clone(&self) -> Node<'e>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'e> Debug for Node<'e>

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

Formats the value using the given formatter.

impl<'e> Default for Node<'e>

fn default() -> Node<'e>

Returns the “default value” for a type.

impl<'e> Eq for Node<'e>

impl<'e> Ord for Node<'e>

fn cmp(&self, other: &Node<'e>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'e> PartialEq for Node<'e>

fn eq(&self, other: &Node<'e>) -> 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<'e> PartialOrd for Node<'e>

fn partial_cmp(&self, other: &Node<'e>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'e> StructuralPartialEq for Node<'e>

impl<'e> TryFrom<Node<'e>> for Edn<'e>

fn try_from(_: Node<'e>) -> Result<Self>

Elaborates a concrete Node into an abstract resolved Edn

#[cfg(feature = "unstable")]
{
  use clojure_reader::{parse, edn::Edn};

  let edn: Edn = parse::Node::no_discards(parse::NodeKind::Nil, parse::Span::default())
    .try_into()
    .unwrap();

  assert_eq!(edn, Edn::Nil);
}

Errors

See crate::error::Error.

type Error = Error

The type returned in the event of a conversion error.
