Struct Span 

pub struct Span {
    pub begin: Position,
    pub end: Position,
}

A Span represents an arbitrary source range. It includes the beginning and ending Positions.

Fields

begin: Position

end: Position

Implementations

impl Span

pub fn new( begin_line: usize, begin_column: usize, end_line: usize, end_column: usize, ) -> Self

Create a new Span. The beginning and ending Positions will also be created.

Arguments

• begin_line The line number for the beginning of the Span, where the first line of the file is at zero.
• begin_column The column number for the beginning of the Span, where the first column of a line is at zero.
• end_line The line number for the ending of the Span, where the first line of the file is at zero.
• end_column The column number for the ending of the Span, where the first column of a line is at zero.

Return

A new Span, with new beginning and ending Positions.

pub fn from_begin_end<Pos>(begin: Pos, end: Pos) -> Self

where Pos: Into<Position>,

Create a new Span from beginning and ending positions.

Arguments

• begin The beginning position.
• end The ending position.

Return

A new Span, with the beginning and ending Positions.

pub fn merge(self, other: Span) -> Span

Trait Implementations

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() -> Self

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 Ord for Span

fn cmp(&self, other: &Span) -> 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 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 PartialOrd for Span

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