Struct Registry

pub struct Registry { /* private fields */ }

Core registry for conversion function lookup

The registry maps function names to actual function pointers. This enables runtime dispatch without code generation.

Implementations

impl Registry

pub fn new() -> Self

Create new empty registry

pub fn register_print_conv( &mut self, name: impl Into<String>, func: PrintConvFn, )

Register a PrintConv function

Arguments

• name - Function name (e.g., “exif_orientation”)
• func - Function pointer

pub fn register_value_conv( &mut self, name: impl Into<String>, func: ValueConvFn, )

Register a ValueConv function

Arguments

• name - Function name (e.g., “apex_shutter_speed”)
• func - Function pointer

pub fn apply_print_conv(&mut self, name: &str, value: &TagValue) -> TagValue

Look up and execute a PrintConv function

Arguments

• name - Function name to look up
• value - Value to convert

Returns

Converted value (string or numeric), or the original value if not found

pub fn apply_value_conv(&mut self, name: &str, value: &TagValue) -> TagValue

Look up and execute a ValueConv function

Arguments

• name - Function name to look up
• value - Value to convert

Returns

Converted value, or original value if not found or conversion failed

pub fn get_missing_print_conv(&self) -> Vec<String>

Get list of missing PrintConv implementations

pub fn get_missing_value_conv(&self) -> Vec<String>

Get list of missing ValueConv implementations

pub fn get_print_conv_stats(&self) -> (usize, usize, usize)

Get PrintConv coverage statistics

pub fn clear_missing_tracking(&mut self)

Clear all missing implementation tracking (useful for testing)

Trait Implementations

impl Debug for Registry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Registry

fn default() -> Self

Returns the “default value” for a type.
