Enum body_image::BodyReader

pub enum BodyReader<'a> {
    Contiguous(Cursor<&'a [u8]>),
    Scattered(GatheringReader<'a, Bytes>),
    File(ReadPos),
    FileSlice(ReadSlice),
}

Provides a Read reference for a BodyImage in any state.

Variants

Contiguous(Cursor<&'a [u8]>)

Cursor over a contiguous single RAM buffer, from Ram or MemMap. Also used for the empty case. Cursor::into_inner may be used for direct access to the memory byte slice.

Scattered(GatheringReader<'a, Bytes>)

GatheringReader providing Read over 2 or more scattered RAM buffers.

File(ReadPos)

ReadPos providing instance independent, unbuffered Read and Seek for BodyImage FsRead state. Consider wrapping this in std::io::BufReader if performing many small reads.

FileSlice(ReadSlice)

ReadSlice providing instance independent, unbuffered Read and Seek for BodyImage FsRead state, limited to a range within an underlying file. Consider wrapping this in std::io::BufReader if performing many small reads.

Methods

impl<'a> BodyReader<'a>

pub fn as_read(&mut self) -> &mut Read

Return the Read reference.
