pub enum RunCommand {
    Print(Invocation),
    Run(Invocation, Comparison, Vec<DataValue>),
}

A run command appearing in a test file.

Variants

Print(Invocation)

Invoke a function and print its result.

Run(Invocation, Comparison, Vec<DataValue>)

Invoke a function and compare its result to a value sequence.

Implementations

impl RunCommand

pub fn run<F>(&self, invoke_fn: F) -> Result<(), String>

where F: FnOnce(&str, &[DataValue]) -> Result<Vec<DataValue>, String>,

Run the RunCommand:

• for RunCommand::Print, print the returned values from invoking the function.
• for RunCommand::Run, compare the returned values from the invoked function and return an Err with a descriptive string if the comparison fails.

Accepts a function used for invoking the actual execution of the command. This function, invoked_fn, is passed the function name and function arguments of the Invocation.

Trait Implementations

impl Debug for RunCommand

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for RunCommand

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for RunCommand

fn eq(&self, other: &RunCommand) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
