Trait tectonic_io_base::InputFeatures

pub trait InputFeatures: Read {
    pub fn get_size(&mut self) -> Result<usize>;
    pub fn try_seek(&mut self, pos: SeekFrom) -> Result<u64>;

    pub fn get_unix_mtime(&mut self) -> Result<Option<i64>> { ... }
}

An extension to the basic Read trait supporting additional features needed for Tectonic's I/O system.

Required methods

pub fn get_size(&mut self) -> Result<usize>

Get the size of the stream. Return TectonicIoError::NotSizeable if the operation is not well-defined for this stream.

pub fn try_seek(&mut self, pos: SeekFrom) -> Result<u64>

Try to seek within the stream. Return TectonicIoError::NotSeekable if the operation is not possible for this stream.

Provided methods

pub fn get_unix_mtime(&mut self) -> Result<Option<i64>>

Get the modification time of this file as a Unix time. If that quantity is not meaningfully defined for this input, return Ok(None). This is what the default implementation does.
