Struct Entry 

pub struct Entry<'a> {
    pub tag: u16,
    pub typ: u16,
    pub count: u32,
    pub order: ByteOrder,
    pub data: &'a [u8],
    pub value_field: u32,
    pub value_pos: usize,
}

A single IFD entry. data holds the raw value bytes (inline or referenced).

Fields

tag: u16

typ: u16

count: u32

order: ByteOrder

data: &'a [u8]

Raw value bytes (count * type_size bytes, possibly truncated if lenient).

value_field: u32

The raw 4-byte value/offset field (offset relative to the IFD base).

value_pos: usize

Absolute position of the value bytes inside the slice the TIFF was parsed from.

Implementations

impl<'a> Entry<'a>

pub fn len(&self) -> usize
