Trait gstreamer::prelude::OptionCheckedDiv

pub trait OptionCheckedDiv<Rhs = Self, InnerRhs = Rhs> {
    type Output;

    // Required method
    fn opt_checked_div(self, rhs: Rhs) -> Result<Option<Self::Output>, Error>;
}
Expand description

Trait for values and Options checked division.

Implementing this trait leads to the following auto-implementations:

  • OptionCheckedDiv<Option<InnerRhs>> for T.
  • OptionCheckedDiv<Rhs> for Option<T>.
  • OptionCheckedDiv<Option<InnerRhs>> for Option<T>.
  • … and some variants with references.

Note that since the std library doesn’t define any CheckedDiv trait, users must provide the base implementation for the inner type.

Required Associated Types§

type Output

The resulting inner type after applying the division.

Required Methods§

fn opt_checked_div(self, rhs: Rhs) -> Result<Option<Self::Output>, Error>

Computes the checked division.

  • Returns Ok(Some(result)) if result could be computed.
  • Returns Ok(None) if at least one argument is None.
  • Returns Err(Error::Overflow) if an overflow occured.
  • Returns Err(Error::DivisionByZero) if rhs is zero.
