Struct RopeC 

pub struct RopeC(pub LineIndex);

Component containing the current source code as a LineIndex, used for LSP byte ↔ position conversions.

Tuple Fields

0: LineIndex

Methods from Deref<Target = LineIndex>

pub fn as_str(&self) -> &str

The full source text.

pub fn len_bytes(&self) -> usize

Total length in bytes.

pub fn len_lines(&self) -> usize

Number of lines (a trailing newline counts as starting one more line).

pub fn line_start(&self, line: usize) -> Option<usize>

Byte offset at which line starts, or None if out of range. A one-past-the-end line is not accepted (use [len_bytes] for that).

pub fn line_byte_range(&self, line: usize) -> Option<Range<usize>>

Byte range [start, end) of line, including its trailing newline (if any).

pub fn line_str(&self, line: usize) -> Option<&str>

Text of line, including its trailing newline (if any).

pub fn byte_slice(&self, range: Range<usize>) -> Option<&str>

Sub-slice by byte range. Returns None for out-of-bounds ranges or ranges that do not fall on char boundaries.

pub fn char_at_byte(&self, byte: usize) -> Option<char>

The char starting at byte offset byte, if byte is a char boundary within the text.

pub fn byte_to_position( &self, byte: usize, encoding: PositionEncoding, ) -> Option<Position>

Convert a byte offset to an LSP Position in the given encoding.

Accepts byte == len_bytes() (end of document). Returns None if byte is out of range or not on a char boundary.

pub fn position_to_byte( &self, position: Position, encoding: PositionEncoding, ) -> Option<usize>

Convert an LSP Position (interpreted in encoding) to a byte offset.

A character past the end of its line is clamped to the line’s end (which keeps the lenient behaviour editors rely on when the cursor sits after the last character). Returns None only if the line itself is out of range.

Trait Implementations

impl AsMut<LineIndex> for RopeC

fn as_mut(&mut self) -> &mut LineIndex

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<LineIndex> for RopeC

fn as_ref(&self) -> &LineIndex

Converts this type into a shared reference of the (usually inferred) input type.

impl Component for RopeC

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have Component<Mutability = Mutable>, while immutable components will instead have Component<Mutability = Immutable>.

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns ComponentRelationshipAccessor required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add ComponentHook for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert ComponentHook for this Component if one is defined.

fn on_replace() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_replace ComponentHook for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove ComponentHook for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn ComponentHook for this Component if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]

impl Debug for RopeC

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

Formats the value using the given formatter.

impl Default for RopeC

fn default() -> RopeC

Returns the “default value” for a type.

impl Deref for RopeC

type Target = LineIndex

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for RopeC

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
