Struct Span 

pub struct Span {
    pub byte_start: usize,
    pub byte_end: usize,
    pub line_start: usize,
    pub line_end: usize,
}

Fields

byte_start: usize

byte_end: usize

line_start: usize

line_end: usize

Implementations

impl Span

pub fn new( byte_start: usize, byte_end: usize, line_start: usize, line_end: usize, ) -> Result<Self>

Create a new Span with validation

pub fn new_unchecked( byte_start: usize, byte_end: usize, line_start: usize, line_end: usize, ) -> Self

Create a new Span without validation (for backward compatibility)

Safety

The caller must ensure the span is valid. Use new() for validated construction.

pub fn validate(&self) -> Result<()>

Validate span invariants

pub fn is_valid(&self) -> bool

Check if this span is valid

pub fn byte_len(&self) -> usize

Get byte length of the span

pub fn line_count(&self) -> usize

Get line count of the span
