Struct ExifReader 

pub struct ExifReader;

EXIF metadata reader.

Implementations

impl ExifReader

pub fn read(data: &[u8]) -> Result<Vec<Tag>>

Parse EXIF data from a byte slice (starting at the TIFF header).

pub fn read_with_base(data: &[u8], base: usize) -> Result<Vec<Tag>>

Parse EXIF data, adding base (the TIFF header’s offset within the file) to offset-type tags so they read as absolute file offsets, matching ExifTool.

pub fn read_as_named_ifd(data: &[u8], ifd_name: &str) -> Vec<Tag>

Parse a TIFF where IFD0 is treated as a named IFD (e.g. “GPS”, “ExifIFD”). Used for CR3 CMT4 (GPS-only TIFF) and CMT2 (ExifIFD-only TIFF). Does no MakerNote/IFD1 processing.

pub fn read_ifd_at( data: &[u8], little_endian: bool, offset: u32, ifd_name: &str, ) -> Vec<Tag>

Parse a single IFD located at offset inside a TIFF-like container whose header this reader cannot parse itself (RW2 uses magic 0x55 instead of 0x2A). Offsets inside the IFD stay relative to the start of data, which is what a TIFF IFD always uses. No ExifByteOrder and no IFD1 chaining.
