Struct FastFieldTocEntry 

pub struct FastFieldTocEntry {
    pub field_id: u32,
    pub column_type: FastFieldColumnType,
    pub multi: bool,
    pub data_offset: u64,
    pub data_len: u64,
    pub num_docs: u32,
    pub dict_offset: u64,
    pub dict_count: u32,
}

On-disk TOC entry for a fast-field column (FST2 format).

Wire: field_id(4) + column_type(1) + flags(1) + data_offset(8) + data_len(8) + num_docs(4) + dict_offset(8) + dict_count(4) = 38 bytes

The flags byte encodes: bit 0: multi-valued column (offset+value sub-columns)

For multi-valued columns, the data region contains: [offset column (auto-codec)] [value column (auto-codec)] with a 4-byte length prefix for the offset column so the reader knows where the value column starts.

Fields

field_id: u32

column_type: FastFieldColumnType

multi: bool

data_offset: u64

data_len: u64

num_docs: u32

dict_offset: u64

Byte offset of the text dictionary section (0 for numeric columns).

dict_count: u32

Number of entries in the text dictionary (0 for numeric columns).
