Struct tectonic::io::FilesystemIo
source · pub struct FilesystemIo { /* private fields */ }
Expand description
FilesystemIo is an I/O provider that reads, and optionally writes, files from a given root directory.
NOTE: no effort is made to contain I/O within the specified root!! We have
an option to disallow absolute paths, but we don’t do anything about
../../../....
paths.

source§fn output_open_name(&mut self, name: &str) -> OpenResult<OutputHandle>
fn output_open_name(&mut self, name: &str) -> OpenResult<OutputHandle>
Open the named file for output.
source§fn output_open_stdout(&mut self) -> OpenResult<OutputHandle>
fn output_open_stdout(&mut self) -> OpenResult<OutputHandle>
Open the standard output stream.
source§fn input_open_name(
&mut self,
name: &str,
status: &mut dyn StatusBackend
) -> OpenResult<InputHandle>
fn input_open_name( &mut self, name: &str, status: &mut dyn StatusBackend ) -> OpenResult<InputHandle>
Open the named file for input.

&mut self,
name: &str,
status: &mut dyn StatusBackend
) -> OpenResult<(InputHandle, Option<PathBuf>)>
fn input_open_name_with_abspath( &mut self, name: &str, status: &mut dyn StatusBackend ) -> OpenResult<(InputHandle, Option<PathBuf>)>
Open the named file for input and return filesystem path information. Read more
source§fn input_open_primary(
&mut self,
_status: &mut dyn StatusBackend
) -> OpenResult<InputHandle>
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.

&mut self,
status: &mut dyn StatusBackend
) -> OpenResult<(InputHandle, Option<PathBuf>)>
fn input_open_primary_with_abspath( &mut self, status: &mut dyn StatusBackend ) -> OpenResult<(InputHandle, Option<PathBuf>)>
Open the primary input and return filesystem path information. Read more
source§fn input_open_format(
&mut self,
name: &str,
status: &mut dyn StatusBackend
) -> OpenResult<InputHandle>
fn input_open_format( &mut self, name: &str, 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.
source§fn write_format(
&mut self,
_name: &str,
_data: &[u8],
_status: &mut dyn StatusBackend
) -> Result<(), Error>
fn write_format( &mut self, _name: &str, _data: &[u8], _status: &mut dyn StatusBackend ) -> Result<(), Error>
Save an a format dump in some way that this provider may be able to
recover in the future. This awkward interface is needed to write
formats with their special munged file names.
