Struct fe_parser::node::Span

pub struct Span {
    pub file_id: SourceFileId,
    pub start: usize,
    pub end: usize,
}

An exclusive span of byte offsets in a source file.

Fields

file_id: SourceFileId

start: usize

A byte offset specifying the inclusive start of a span.

end: usize

A byte offset specifying the exclusive end of a span.

fn add(self, other: &'a T) -> Span

Performs the + operation.

impl<'a> Add<&Token<'a>> for Span

type Output = Span

The resulting type after applying the + operator.

fn add(self, other: &Token<'a>) -> Self

Performs the + operation.

impl<'a, T> Add<Option<&'a T>> for Spanwhere Span: Add<&'a T, Output = Span>,

type Output = Span

The resulting type after applying the + operator.

fn add(self, other: Option<&'a T>) -> Span

Performs the + operation.

impl Add<Option<Span>> for Span

type Output = Span

The resulting type after applying the + operator.

fn add(self, other: Option<Span>) -> Span

Performs the + operation.

impl Add for Span

type Output = Span

The resulting type after applying the + operator.

fn add(self, other: Span) -> Span

Performs the + operation.

impl<T> AddAssign<T> for Spanwhere Span: Add<T, Output = Span>,

fn add_assign(&mut self, other: T)

Performs the += operation.

impl Clone for Span

fn clone(&self) -> Span

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Span

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Span

fn deserialize<__D>( __deserializer: __D ) -> Result<Span, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<&Box<Node<T>>> for Span

fn from(node: &Box<Node<T>>) -> Self

Converts to this type from the input type.

impl<T> From<&Node<T>> for Span

fn from(node: &Node<T>) -> Self

Converts to this type from the input type.

impl Hash for Span

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

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 Span

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

impl Serialize for Span

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
