Implementations

impl Checker

pub fn is_empty(&self) -> bool

An empty checker contains no directives, and will match any input string.

pub fn check(&self, text: &str, vars: &dyn VariableMap) -> Result<bool>

Verify directives against the input text.

This returns true if the text matches all the directives, false if it doesn’t. An error is only returned if there is a problem with the directives.

pub fn explain( &self, text: &str, vars: &dyn VariableMap, ) -> Result<(bool, String)>

Explain how directives are matched against the input text.
