Struct TextRange 

pub struct TextRange {
    pub start: usize,
    pub end: usize,
}

A byte range within a document’s source string.

Fields

start: usize

Inclusive start byte offset.

end: usize

Exclusive end byte offset.

Implementations

impl TextRange

pub fn try_new(start: usize, end: usize) -> Result<Self, RangeError>

Creates a new TextRange, validating that start <= end.

Bounds and UTF-8 boundary checks require the source string, so they happen in DocumentChange::try_apply, not here.

pub fn new(start: usize, end: usize) -> Self

👎Deprecated:

panics on invalid input (start > end); use try_new

Creates a new TextRange.

pub fn len(&self) -> usize

Returns the number of bytes covered by this range.

pub fn is_empty(&self) -> bool

Returns true if the range covers zero bytes.
