Function render_anyhow_error 

pub fn render_anyhow_error(err: &Error, source_map: &SourceMap) -> String

Renders an anyhow::Error chain produced by this crate, substituting snippet-bearing output for any ResolveError or ParseError layers.

For each layer in the chain, this calls ResolveError::render or ParseError::render to format typed errors with file/line/column and a source snippet. Other layers are formatted via their fmt::Display impl. Layers are joined with ": ", matching format!("{err:#}").

source_map must be the SourceMap in which every typed error’s spans are valid; combining typed errors from different source maps in one chain is unsupported. For errors from Resolve methods, prefer Resolve::render_error.
