Struct lumberjack::io::AbsoluteEncoding

pub struct AbsoluteEncoding(_);

Absolute Encoding.

Trees are encoded as a sequence of tuples:

• For each token a the common nonterminal label with the following token and the number of common nonterminal nodes.
• Optional leaf unary chains.

Methods

impl AbsoluteEncoding

pub fn new(inner: Vec<(Option<AbsoluteAncestor>, Option<String>)>) -> Self

pub fn try_from_relative(encoding: RelativeEncoding) -> ConversionResult

Fallible conversion from RelativeEncoding.

Returns: * ConversionResult::Success if conversion was succesful or * ConversionResult::Error if an error was encountered.

Errors are recoverable, and can be fixed by e.g.:

use lumberjack::io::{AbsoluteEncoding, Encode, PTBFormat};

let tree = PTBFormat::Simple.string_to_tree("(Some (Test tree))").unwrap();
let rel_encoding = tree.encode_relative().unwrap();
let abs_encoding = AbsoluteEncoding::try_from_relative(rel_encoding).unwrap_or_fix();;

Methods from Deref<Target = Vec<(Option<AbsoluteAncestor>, Option<String>)>>

pub fn capacity(&self) -> usize

Returns the number of elements the vector can hold without reallocating.

Examples

let vec: Vec<i32> = Vec::with_capacity(10);
assert_eq!(vec.capacity(), 10);

pub fn as_slice(&self) -> &[T]

Extracts a slice containing the entire vector.

Equivalent to &s[..].

Examples

use std::io::{self, Write};
let buffer = vec![1, 2, 3, 5, 8];
io::sink().write(buffer.as_slice()).unwrap();

pub fn len(&self) -> usize

Returns the number of elements in the vector, also referred to as its 'length'.

Examples

let a = vec![1, 2, 3];
assert_eq!(a.len(), 3);

pub fn is_empty(&self) -> bool

Returns true if the vector contains no elements.

Examples

let mut v = Vec::new();
assert!(v.is_empty());

v.push(1);
assert!(!v.is_empty());

Trait Implementations

impl PartialEq<AbsoluteEncoding> for AbsoluteEncoding

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

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

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

This method tests for !=.

impl From<AbsoluteEncoding> for RelativeEncoding

fn from(encoding: AbsoluteEncoding) -> Self

Performs the conversion.

impl Clone for AbsoluteEncoding

fn clone(&self) -> AbsoluteEncoding

Returns a copy of the value.

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

Performs copy-assignment from source.

impl IntoIterator for AbsoluteEncoding

type Item = (Option<AbsoluteAncestor>, Option<String>)

The type of the elements being iterated over.

type IntoIter = IntoIter<Self::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Debug for AbsoluteEncoding

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

Formats the value using the given formatter.

impl Deref for AbsoluteEncoding

type Target = Vec<(Option<AbsoluteAncestor>, Option<String>)>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
