Struct enso_data::text::Span

pub struct Span {
    pub index: Index,
    pub size: Size,
}

Strongly typed span into container with index and size.

Fields

index: Index

size: Size

Implementations

impl Span

pub fn new(index: Index, size: Size) -> Self

Initializes Span with given values.

pub fn from_indices(begin: Index, end: Index) -> Self

Creates a span describing a range between two indices.

pub fn from_beginning_to(index: Index) -> Self

Creates a span from zero up to given index.

pub fn from_beginning(size: Size) -> Self

Creates a span from zero index with given length.

pub fn last(&self) -> Option<Index>

Get the index of the last character in the span.

If the span is empty returns None.

pub fn end(&self) -> Index

Get the character after last character of this span.

If span has size 0, it returns the index field.

pub fn contains(&self, index: Index) -> bool

Check if this span contains character under index.

pub fn contains_span(&self, span: &Span) -> bool

Check if this span contains the whole another span.

pub fn range(self) -> Range<usize>

Converts span to Range<usize>.

pub fn extend_left(&mut self, size: Size)

Expand the span by moving its left (start) index.

pub fn extend_right(&mut self, size: Size)

Expand the span by moving its right (end) index.

pub fn shrink_left(&mut self, size: Size)

Shrink the span by moving its left (start) index.

pub fn shrink_right(&mut self, size: Size)

Shrink the span by moving its right (end) index.

pub fn move_left(&mut self, size: Size)

Move the whole span left, maintaining its size.

pub fn move_right(&mut self, size: Size)

Move the whole span right, maintaining its size.

pub fn set_left(&mut self, new_left: Index)

Move the start index of the span, adjusting the size.

pub fn set_right(&mut self, new_right: Index)

Move the end index of the span, adjusting the size.

pub fn is_empty(self) -> bool

Check if this is an empty span (zero elements).
