pub fn read_capped(file: File, max_bytes: usize) -> Result<(Vec<u8>, bool)>Expand description
Like read_file_capped, but reads from an already-open std::fs::File.
Used when the caller has obtained the handle through a confinement-checked
open (e.g. mermaid_runtime::open_beneath) and must read the same inode
the check resolved — feeding a path back to read_file_capped would reopen
by name and reintroduce the symlink TOCTOU (#77).
