Struct Anchor 

pub struct Anchor {
    pub expansion: SourceRange,
    pub definition: Option<SourceRange>,
}

Where a node is, and where it was written.

Fields

expansion: SourceRange

Where the code sits in the file being read. Syntax fragments are cut from here, so this is what a node anchors to.

definition: Option<SourceRange>

Where the code was written, when that is somewhere else — inside a macro body, or in the template this instantiation came from.

None for code that is where it was written.

Implementations

impl Anchor

pub const fn written_here(range: SourceRange) -> Self

An anchor for code that is where it was written.

pub const fn is_expanded(&self) -> bool

Whether this node was produced somewhere other than where it reads.
