Struct Span 

pub struct Span {
    pub file_id: FileId,
    pub byte_start: u32,
    pub byte_end: u32,
    pub line_start: u32,
    pub col_start: u32,
    pub line_end: u32,
    pub col_end: u32,
}

Source location span within a file.

Byte offsets are absolute within the file; line/column are 1-based.

Fields

file_id: FileId

Unique identifier for the source file.

byte_start: u32

Byte offset of span start (0-based).

byte_end: u32

Byte offset of span end (exclusive, 0-based).

line_start: u32

Line number of span start (1-based).

col_start: u32

Column number of span start (1-based).

line_end: u32

Line number of span end (1-based).

col_end: u32

Column number of span end (1-based).

Implementations

impl Span

pub const fn new( file_id: FileId, byte_start: u32, byte_end: u32, line_start: u32, col_start: u32, line_end: u32, col_end: u32, ) -> Self

Create a new span.

pub const fn point( file_id: FileId, byte_offset: u32, line: u32, col: u32, ) -> Self

Create a point span (single 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<'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 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 Eq for Span
