Struct lexical_bool::LexicalBool

pub struct LexicalBool(_);

LexicalBool allows parsing truthy-like strings to a bool

It can be deref (e.g. *lb) to get the bool, or compared to a bool (e.g. lb == false)

This uses the values provided by initialize_true_values and initialize_false_values.

If they were not initialized before the first parse, than the defaults of TRUTHY_VALUES and FALSEY_VALUES are used for the life of the thread it was parsed from.

note The parsing is case-insensitive

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Display for LexicalBool

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

Formats the value using the given formatter.

impl Debug for LexicalBool

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

impl FromStr for LexicalBool

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Deref for LexicalBool

type Target = bool

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Hash for LexicalBool

fn hash<__H: Hasher>(&self, state: &mut __H)
