Module source 

Input abstraction. A container never opens a file — it asks a Source what it can do, and the ladder (see crate::ladder) supplies the best rung.

Modules

decode_side

Marking a Source as sitting BELOW a codec decoder.

limit

Decompression-bomb protection.

spill

Rung 3 of the ladder: spool a non-seekable input so it becomes seekable.

stream_only

Adapter presenting a plain reader as a non-seekable Source.

Structs

FileSource

A seekable source backed by a real file. The Exact rung.

GuardedSeek

Wraps a seekable reader so a rejected seek POSITION is reported as malformed input rather than as an i/o failure of the medium.

PeekSource

Wraps a source so a bounded prefix can be inspected and then replayed.

ReaderSource

A forward-only source. Models “arrived on a pipe” — it erases any seek ability the underlying reader might happen to have, so tests can exercise the non-seekable path deterministically.

SourceCaps

Constants

MAX_SEEK_POSITION

The largest absolute position any platform in scope can address: a file offset is an i64 on every unix and on Windows alike, so a u64 above this names a location no file can ever hold.

Traits

SeekRead

Blanket-implemented marker so &mut dyn SeekRead is usable as a trait object.

Source

An input stream that reports its own capabilities.
