Struct tectonic::io::cached_itarbundle::CachedITarBundle

pub struct CachedITarBundle { /* fields omitted */ }

Bundle provided by an indexed tar file over http with a local cache.

Implementations

impl CachedITarBundle

pub fn new(
    url: &str,
    only_cached: bool,
    custom_cache_root: Option<&Path>,
    status: &mut dyn StatusBackend
) -> Result<CachedITarBundle>

Trait Implementations

impl Bundle for CachedITarBundle

fn get_digest(&mut self, _status: &mut dyn StatusBackend) -> Result<DigestData>

Get a cryptographic digest summarizing this bundle’s contents.

impl Clone for CachedITarBundle

fn clone(&self) -> CachedITarBundle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CachedITarBundle

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

Formats the value using the given formatter.

impl IoProvider for CachedITarBundle

fn input_open_name(
    &mut self,
    name: &OsStr,
    status: &mut dyn StatusBackend
) -> OpenResult<InputHandle>

fn output_open_name(&mut self, _name: &OsStr) -> OpenResult<OutputHandle>

fn output_open_stdout(&mut self) -> OpenResult<OutputHandle>

fn input_open_primary(
    &mut self,
    _status: &mut dyn StatusBackend
) -> OpenResult<InputHandle>

Open the "primary" input file, which in the context of TeX is the main input that it's given. When the build is being done using the filesystem and the input is a file on the filesystem, this function isn't necesssarily that important, but those conditions don't always hold.

fn input_open_format(
    &mut self,
    name: &OsStr,
    status: &mut dyn StatusBackend
) -> OpenResult<InputHandle>

Open a format file with the specified name. Format files have a specialized entry point because IOProviders may wish to handle them specially: namely, to munge the filename to one that includes the current version of the Tectonic engine, since the format contents depend sensitively on the engine internals.

fn write_format(
    &mut self,
    _name: &str,
    _data: &[u8],
    _status: &mut dyn StatusBackend
) -> Result<()>

Save an a format dump in some way that this provider may be able to recover in the future. This awkward interface is needed for to write formats with their special munged file names.
