Implementations

impl<'a> SyntaxRewriter<'a>

pub fn from_fn(
    f: impl Fn(&SyntaxElement) -> Option<SyntaxElement> + 'a
) -> SyntaxRewriter<'a>

pub fn delete<T: Clone + Into<SyntaxElement>>(&mut self, what: &T)

pub fn replace<T: Clone + Into<SyntaxElement>>(&mut self, what: &T, with: &T)

pub fn replace_with_many<T: Clone + Into<SyntaxElement>>(
    &mut self,
    what: &T,
    with: Vec<SyntaxElement>
)

pub fn replace_ast<T: AstNode>(&mut self, what: &T, with: &T)

pub fn rewrite(&self, node: &SyntaxNode) -> SyntaxNode

pub fn rewrite_ast<N: AstNode>(self, node: &N) -> N

pub fn rewrite_root(&self) -> Option<SyntaxNode>

Returns a node that encompasses all replacements to be done by this rewriter.

Passing the returned node to rewrite will apply all replacements queued up in self.

Returns None when there are no replacements.
