Struct Signature 

pub struct Signature {
    pub filter: Option<String>,
    pub sub_filter: Option<String>,
    pub byte_range: Vec<(u64, u64)>,
    pub contents: Vec<u8>,
    pub name: Option<String>,
    pub signing_time: Option<String>,
    pub location: Option<String>,
    pub reason: Option<String>,
    pub contact_info: Option<String>,
}

A signature dictionary (ISO 32000-1 §12.8.1, Table 252) as the value of a signature field, read as data: nothing here is verified.

Covers ISO 32000-1 §12.8.1.

Fields

filter: Option<String>

/Filter: the preferred signature handler.

sub_filter: Option<String>

/SubFilter: the encoding of the signature value and key information, such as adbe.pkcs7.detached.

byte_range: Vec<(u64, u64)>

/ByteRange: the (offset, length) pairs of the bytes the digest covers; an incomplete pair or a negative number ends the list.

contents: Vec<u8>

/Contents: the signature value as written; empty when absent.

name: Option<String>

/Name: the signer named in the dictionary.

signing_time: Option<String>

/M: the time of signing as written, a PDF date string.

location: Option<String>

/Location: where the signing took place.

reason: Option<String>

/Reason: why the document was signed.

contact_info: Option<String>

/ContactInfo: how to reach the signer.

Implementations

impl Signature

pub fn from_dict(dict: &Dict) -> Signature

The Table 252 entries of a signature dictionary as data: the filter and sub-filter names, the byte range pairs, the contents bytes, and the signer’s name, time, location, reason and contact information as text strings. Nothing is verified. The same reader serves a signature field’s /V (§12.7.4.5) and the catalog’s permission handlers (§12.8.4).

Covers ISO 32000-1 §12.8.1.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl Default for Signature

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Signature

impl PartialEq for Signature

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
