Struct pdf_writer::writers::FileSpec

pub struct FileSpec<'a> { /* private fields */ }

Writer for a file specification dictionary.

This struct is created by Annotation::file_spec, Reference::file_spec, and Action::file_spec.

Implementations

impl<'a> FileSpec<'a>

pub fn file_system(&mut self, system: Name<'_>) -> &mut Self

Write the /FS attribute to set the file system this entry relates to. If you set the system argument to Name(b"URL"), this becomes an URL specification.

pub fn path(&mut self, path: Str<'_>) -> &mut Self

Write the /F attribute to set the file path. Directories are indicated by /, independent of the platform.

pub fn unic_file(&mut self, path: TextStr<'_>) -> &mut Self

Write the /UF attribute to set a Unicode-compatible path. Directories are indicated by /, independent of the platform. PDF 1.7+.

pub fn volatile(&mut self, dont_cache: bool) -> &mut Self

Write the /V attribute to indicate whether not to cache the file.

pub fn description(&mut self, desc: TextStr<'_>) -> &mut Self

Write the /Desc attribute to set a file description. PDF 1.6+.

pub fn embedded_file(&mut self, id: Ref) -> &mut Self

Write the /EF attribute to reference an embedded file. PDF 1.3+.

This only sets an embedded file for the F attribute corresponding to the path method. You will need to write this dictionary manually if you need to set UF.

Methods from Deref<Target = Dict<'a>>

pub fn len(&self) -> i32

The number of written pairs.

pub fn is_empty(&self) -> bool

Whether no pairs have been written so far.

pub fn insert(&mut self, key: Name<'_>) -> Obj<'_>

Start writing a pair with an arbitrary value.

pub fn pair<T: Primitive>(&mut self, key: Name<'_>, value: T) -> &mut Self

Write a pair with a primitive value.

This is a shorthand for dict.insert(key).primitive(value).

pub fn pairs<'n, T: Primitive>( &mut self, pairs: impl IntoIterator<Item = (Name<'n>, T)> ) -> &mut Self

Write a sequence of pairs with primitive values.
