Struct ParsedReplacementBody 

pub struct ParsedReplacementBody {
    pub source: String,
    pub tree: Tree,
    pub body_offset: usize,
    pub parameters: Vec<String>,
}

A function-like macro replacement parsed inside a sentinel function body.

Tree-sitter keeps a #define NAME(a) ... replacement as one opaque preproc_arg. Wrapping that exact byte slice in a function body recovers its statements, declarations, and member calls as ordinary C++ structure. The slice is copied verbatim at Self::body_offset, so a node range in Self::tree maps back onto the defining preproc_arg by subtracting that offset.

Fields

source: String

tree: Tree

body_offset: usize

parameters: Vec<String>

Implementations

impl ParsedReplacementBody

pub fn statements(&self) -> Option<Node<'_>>

The sentinel function body holding the replacement’s statements.

pub fn file_range( &self, node: Node<'_>, replacement_start: usize, ) -> Range<usize>

The byte range node occupies in the file that defines the macro.

replacement_start is the defining preproc_arg’s start byte. The replacement is copied into the sentinel verbatim, so subtracting the body offset and adding that start is exact.
