Struct FrameHeaderInfo 

pub struct FrameHeaderInfo {
    pub content_size: FrameContentSize,
    pub window_size: u64,
    pub dictionary_id: Option<u32>,
    pub content_checksum: bool,
    pub header_size: usize,
}

Frame header fields decoded by read_frame_header_info, mirroring the values the C ZSTD_getFrameHeader fills into a ZSTD_FrameHeader.

Fields

content_size: FrameContentSize

Declared decompressed size, or FrameContentSize::Unknown when the header omits the Frame_Content_Size field.

window_size: u64

Decoder window size in bytes (the minimum buffer needed to decode the frame). For single-segment frames this equals the content size.

dictionary_id: Option<u32>

Dictionary id required to decode the frame, if the header carries one.

content_checksum: bool

Whether a 32-bit content checksum trails the frame.

header_size: usize

Header length in bytes, measured in the parsed input format: it includes the 4-byte magic number in the default format, but excludes it when parsed as magicless (read_frame_header_info(.., true)), since those 4 bytes are not present on the wire in that mode.
