Struct Span 

pub struct Span {
    pub offset: usize,
}

Span represent an error location within a file.

Currently, it is just an offset in byte within the file.

When the proc_macro_span feature is enabled, it may also hold a proc_macro span.

Fields

offset: usize

Implementations

impl Span

pub fn is_valid(&self) -> bool

pub fn new(offset: usize) -> Self

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 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.
