Module rs_buffer_io 

Buffer-based I/O handlers for parsing SAS files from in-memory byte slices.

Provides ReadStatBufferCtx and a set of extern "C" callback functions that implement the ReadStat I/O interface over a &[u8] buffer instead of a file. This enables parsing .sas7bdat data without filesystem access — useful for WASM targets, cloud storage, HTTP uploads, and testing.

Structs

ReadStatBufferCtx

In-memory buffer context for ReadStat I/O callbacks.

Functions

buffer_close 🔒 ^⚠

No-op close handler — nothing to close for an in-memory buffer.

buffer_open 🔒 ^⚠

No-op open handler — the buffer is already “open”.

buffer_read 🔒 ^⚠

Read handler that copies bytes from the buffer into the caller’s buffer.

buffer_seek 🔒 ^⚠

Seek handler that repositions the read cursor within the buffer.

buffer_update 🔒 ^⚠

Update/progress handler for buffer I/O.
