Module ast_grep_core::source

This module defines the Doc and Content traits to abstract away source code encoding issues.

ast-grep supports three kinds of encoding: utf-8 for CLI, utf-16 for nodeJS napi and Vec<char> for wasm. Different encoding will produce different tree-sitter Node’s range and position.

The Content trait is defined to abstract different encoding. It is used as associated type bound Source in the Doc trait. Its associated type Underlying represents the underlying type of the content, e.g. Vec<u8>, Vec<u16>.

Doc is a trait that defines a document that can be parsed by Tree-sitter. It has a Source associated type bounded by Content that represents the source code of the document, and a Lang associated type that represents the language of the document.
