Trait arsert::ExpressionInfo

pub trait ExpressionInfo: Display {
    fn expression(&self) -> String;
    fn values(self) -> HashMap<String, Box<dyn Debug + 'static>, RandomState>;
    fn expression_parts(&self) -> Vec<String>;
}

A trait representing information about the expression that led to a failed assertion.

Required methods

fn expression(&self) -> String

Returns the entire expression, represented as Rust source code in a String.

fn values(self) -> HashMap<String, Box<dyn Debug + 'static>, RandomState>

Returns the actual values that contributed to the assertion failure.

fn expression_parts(&self) -> Vec<String>

Returns the parts of the expression, broken into rust source code in a String.
