Struct SnippetSession 

pub struct SnippetSession { /* private fields */ }

An active snippet session tracked in document coordinates.

This is a view-local editing state: it is expected to be stored alongside cursor/selection state (e.g. per ViewId in a Workspace).

Implementations

impl SnippetSession

pub fn new(insert_start: usize, template: &SnippetTemplate) -> Option<Self>

Create a snippet session for an inserted template.

• insert_start is the character offset where template.text begins in the document.
• Returns None when template contains no tabstops (nothing to navigate).

pub fn is_active(&self) -> bool

Return true if this session has at least one tabstop.

pub fn apply_delta(&mut self, delta: &TextDelta)

Shift all tracked placeholder/final offsets through a document text delta.

Trait Implementations

impl Clone for SnippetSession

fn clone(&self) -> SnippetSession

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnippetSession

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

Formats the value using the given formatter.

impl Eq for SnippetSession

impl PartialEq for SnippetSession

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