Implementations

impl Comparison

pub fn compare<T: Compare + Debug>(&self, a: &T) -> Ternary

pub fn from_string(string: &str) -> Result<Self, ComparisonParseError>

👎Deprecated since 0.9.6:

Use FromStr::from_str or String::parse instead

Errors

When given an invalid comparison operator. Importantly, adding spaces within the operator counts as making it invalid.

Trait Implementations
