Struct Span 

pub struct Span {
    pub offset: usize,
    pub line: u32,
    pub column: usize,
    pub len: usize,
}

Source location: byte offset, line, column, and length in the source file. Line and column are 1-based. Use Span::to_lsp_range for 0-based LSP ranges.

Fields

offset: usize

line: u32

column: usize

len: usize

Implementations

impl Span

pub fn dummy() -> Self

Dummy span for tests or synthetic nodes (offset 0, line 1, column 1, len 0).

pub fn to_lsp_range(&self) -> (u32, u32, u32, u32)

LSP uses 0-based line and 0-based character. Returns (start_line, start_character, end_line, end_character).

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 Eq for Span

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.
