Struct TextSpan 

pub struct TextSpan {
    pub start: TextOffset,
    pub end: TextOffset,
}

A range of text offsets that form a span (like text selection).

Fields

start: TextOffset

end: TextOffset

Implementations

impl TextSpan

pub fn new(start: TextOffset, end: TextOffset) -> TextSpan

Create a new TextSpan.

pub fn call_site() -> Self

Create a new TextSpan, located at the invocation of the current procedural macro. Identifiers created with this span will be resolved as if they were written directly at the macro call location (call-site hygiene).

pub fn start(self) -> Self

Create a new TextSpan, with width 0, located right before this span.

pub fn end(self) -> Self

Create a new TextSpan, with width 0, located right after this span.

Trait Implementations

impl Clone for TextSpan

fn clone(&self) -> TextSpan

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TextSpan

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for TextSpan

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 TextSpan

fn eq(&self, other: &TextSpan) -> 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.
