[−][src]Enum tectonic_io_base::OpenResult

pub enum OpenResult<T> {
    Ok(T),
    NotAvailable,
    Err(Error),
}

A convenience type for file-open operations when "not found" needs to be handled specially.

Variants

Ok(T)

The open operation succeeded.

NotAvailable

The file was not available.

Err(Error)

Something else went wrong.

Implementations

impl<T> OpenResult<T>[src]

pub fn unwrap(self) -> T[src]

Obtain the underlying file object, or panic.

pub fn is_not_available(&self) -> bool[src]

Returns true if this result is of the NotAvailable variant.

pub fn must_exist(self) -> Result<T>[src]

Convert this object into a plain Result, erroring if the item was not available.
