Required Methods§

Source

fn try_mul(self, rhs: Self) -> Result<Self, ValueError>

Similar to std::ops::Mul, but fallible (e.g. TryMul).

Source

fn try_div(self, rhs: Self) -> Result<Self, ValueError>

Similar to std::ops::Div, but fallible (e.g. TryDiv).

Source

fn try_add(self, rhs: Self) -> Result<Self, ValueError>

Similar to std::ops::Add, but fallible (e.g. TryAdd).

Source

fn try_sub(self, rhs: Self) -> Result<Self, ValueError>

Similar to std::ops::Sub, but fallible (e.g. TrySub).

Source

fn try_or( self, rhs: impl FnMut() -> Result<Self, ExpressionError>, ) -> Result<Self, ValueError>

Try to “OR” (||) two values types.

If the lhs value is null or false, the rhs is evaluated and returned. The rhs is a closure that can return an error, and thus this method can return an error as well.
