Struct Span 

pub struct Span {
    pub start_line: u32,
    pub start_col: u32,
    pub end_line: u32,
    pub end_col: u32,
}

A location range in source code.

Fields

start_line: u32

Starting line (1-indexed).

start_col: u32

Starting column (0-indexed, byte offset).

end_line: u32

Ending line (1-indexed).

end_col: u32

Ending column (0-indexed, byte offset).

Implementations

impl Span

pub fn new(start_line: u32, start_col: u32, end_line: u32, end_col: u32) -> Self

Creates a new span from start and end positions.

pub fn point(line: u32, col: u32) -> Self

Creates a single-point span (zero-width).

pub fn line_count(&self) -> u32

Returns the number of lines this span covers.

pub fn contains(&self, line: u32, col: u32) -> bool

Returns true if the given position is within this 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<'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
