Binary data table configuration ExifTool: Tag table with PROCESS_PROC => &ProcessBinaryData

Fields

default_format: BinaryDataFormat

Default format for entries (ExifTool: FORMAT key)

first_entry: Option<u32>

Starting index for unknown tag generation (ExifTool: FIRST_ENTRY key)

groups: HashMap<u8, String>

Group hierarchy for tags (ExifTool: GROUPS key)

tags: HashMap<u32, BinaryDataTag>

Tag definitions indexed by position

data_member_tags: Vec<u32>

Tags that are DataMembers and must be extracted first ExifTool: DATAMEMBER => […] array of indices

dependency_order: Vec<u32>

Processing order for tags with dependencies Phase 1: DataMember tags, Phase 2: dependent tags

Implementations

impl BinaryDataTable

pub fn analyze_dependencies(&mut self)

Check if a tag needs expression evaluation

pub fn get_tag_format_spec(&self, index: u32) -> Option<FormatSpec>

Get effective format for a tag (format_spec takes precedence)
