Struct SourceView 

pub struct SourceView<'view> { /* private fields */ }

A view into a portion of source text.

This struct represents a slice or window into a larger source text, allowing parsers to work with specific sections of code while maintaining proper position tracking and coordinate conversion.

Implementations

impl<'view> SourceView<'view>

pub fn view(&self, range: Range<usize>) -> Self

Creates a new view into a sub-range of this view.

This method allows creating nested views within existing views, enabling parsers to work with increasingly specific sections of code.

Arguments

• range - The relative range within this view to create a sub-view for

Returns

A new SourceView representing the specified sub-range

Trait Implementations

impl<'view> Clone for SourceView<'view>

fn clone(&self) -> SourceView<'view>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'view> Debug for SourceView<'view>

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

Formats the value using the given formatter.

impl<'view> From<&'view SourceText> for SourceView<'view>

fn from(value: &'view SourceText) -> Self

Converts to this type from the input type.

impl<'view> Hash for SourceView<'view>

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<'view> PartialEq for SourceView<'view>

fn eq(&self, other: &SourceView<'view>) -> 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.

Converts a byte range to an LSP Range.

fn lsp_range_to_span(&self, range: Range) -> Range<usize>
