Struct SyntaxEdit

source 
pub struct SyntaxEdit { /* private fields */ }
Expand description

Represents a completed SyntaxEditor operation.

Implementations§

source§

impl SyntaxEdit

source

pub fn old_root(&self) -> &SyntaxNode

Root of the initial unmodified syntax tree.

source

pub fn new_root(&self) -> &SyntaxNode

Root of the modified syntax tree.

source

pub fn changed_elements(&self) -> &[SyntaxElement]

Which syntax elements in the modified syntax tree were inserted or modified as part of the edit.

Note that for syntax nodes, only the upper-most parent of a set of changes is included, not any child elements that may have been modified.

source

pub fn find_annotation(&self, annotation: SyntaxAnnotation) -> &[SyntaxElement]

Finds which syntax elements have been annotated with the given annotation.

Note that an annotation might not appear in the modified syntax tree if the syntax elements that were annotated did not make it into the final syntax tree.
