Struct Span 

pub struct Span {
    pub lo: u32,
    pub hi: u32,
}

The span type which tracks where formatted errors originate from in a Leo file. This is used in many spots throughout the rest of the Leo crates.

Fields

lo: u32

The start (low) position of the span, inclusive.

hi: u32

The end (high) position of the span, exclusive. The length of the span is hi - lo.

Implementations

impl Span

pub fn new(start: u32, end: u32) -> Self

Generate a new span from the starting and ending positions.

pub const fn dummy() -> Self

Generates a dummy span with all defaults. Should only be used in temporary situations.

pub fn is_dummy(&self) -> bool

Is the span a dummy?

Trait Implementations

impl Add for &Span

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

Add two spans (by reference) together.

type Output = Span

The resulting type after applying the + operator.

impl Add for Span

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

Add two spans together. The resulting span is the smallest span that includes both.

type Output = Span

The resulting type after applying the + operator.

impl Clone for Span

fn clone(&self) -> Span

Returns a duplicate 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 Default for Span

fn default() -> Span

Returns the “default value” for a type.

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 Display for Span

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

Formats the value using the given formatter.

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
