Struct ProcessorResult

pub struct ProcessorResult {
    pub extracted_tags: HashMap<String, TagValue>,
    pub warnings: Vec<String>,
    pub next_processors: Vec<(ProcessorKey, ProcessorContext)>,
}

Result returned by processor after processing binary data

This structure encapsulates everything a processor produces, including extracted tags, warnings, and instructions for further processing.

ExifTool Reference

ExifTool processors modify the ExifTool object state and may trigger recursive processing. This structure captures those side effects explicitly.

Fields

extracted_tags: HashMap<String, TagValue>

Tags extracted by the processor Maps tag names to their extracted values

warnings: Vec<String>

Warnings generated during processing Used for non-fatal issues like data corruption or unexpected formats

next_processors: Vec<(ProcessorKey, ProcessorContext)>

Additional processors to run for nested processing Each entry specifies a processor and the context it should use This enables ExifTool’s recursive SubDirectory processing

Implementations

impl ProcessorResult

pub fn new() -> Self

pub fn add_warning(&mut self, warning: String)

Add a warning to the result

pub fn add_tag(&mut self, name: String, value: TagValue)

Add a tag to the extracted results

pub fn add_nested_processor( &mut self, key: ProcessorKey, context: ProcessorContext, )
