Struct 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.

Implementations

pub fn zero(file_id: SourceFileId) -> Self

pub fn dummy() -> Self

pub fn is_dummy(&self) -> bool

pub fn from_pair<S, E>(start_elem: S, end_elem: E) -> Self

where S: Into<Span>, E: Into<Span>,

Trait Implementations

impl<'a, T> Add<&'a T> for Span

where T: Spanned,

type Output = Span

The resulting type after applying the + operator.

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

Performs the + operation.

impl<'a, T> Add<Option<&'a T>> for Span

where Span: Add<&'a T, Output = Self>,

type Output = Span

The resulting type after applying the + operator.

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

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>) -> Self

Performs the + operation.

impl Add for Span

type Output = Span

The resulting type after applying the + operator.

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

Performs the + operation.

impl<T> AddAssign<T> for Span

where Span: Add<T, Output = Self>,

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

Formats the value using the given formatter.

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

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Span> for Range<usize>

fn from(span: Span) -> Self

Converts to this type from the input type.

impl Hash for Span

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

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

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 Serialize for Span

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Span
