Struct BooleanParser 

pub struct BooleanParser { /* private fields */ }

Parses a yes/no answer into a bool.

Matching ignores case, surrounding whitespace, quotes/backticks and a trailing period. Defaults: YES/TRUE are true, NO/FALSE are false. As a chain output parser it yields "true" or "false".

Implementations

impl BooleanParser

pub fn new() -> Self

pub fn with_values<T, F>(self, true_values: T, false_values: F) -> Self

where T: IntoIterator, T::Item: Into<String>, F: IntoIterator, F::Item: Into<String>,

Replaces the words read as true and false (compared case-insensitively).

Trait Implementations
