Struct BooleanConversionOptions 

pub struct BooleanConversionOptions {
    pub case_sensitive: bool,
    /* private fields */
}

Options that control string-to-boolean conversion.

Fields

case_sensitive: bool

Whether literal matching is case-sensitive.

Implementations

impl BooleanConversionOptions

pub fn strict() -> Self

Creates strict boolean conversion options.

Returns

Options accepting true, false, 1, and 0.

pub fn env_friendly() -> Self

Creates options suitable for environment variable values.

Returns

Options accepting true/false, 1/0, yes/no, and on/off.

pub fn true_literals(&self) -> &[String]

Gets the accepted true literals.

Returns

A slice of accepted true literals.

pub fn false_literals(&self) -> &[String]

Gets the accepted false literals.

Returns

A slice of accepted false literals.

pub fn with_case_sensitive(self, case_sensitive: bool) -> Self

Returns a copy with boolean literal matching case sensitivity changed.

Parameters

• case_sensitive - Whether matching is case-sensitive.

Returns

Updated options.

pub fn with_true_literal(self, literal: &str) -> Self

Returns a copy that accepts an additional true literal.

Parameters

• literal - Literal to parse as true.

Returns

Updated options.

pub fn with_false_literal(self, literal: &str) -> Self

Returns a copy that accepts an additional false literal.

Parameters

• literal - Literal to parse as false.

Returns

Updated options.

pub fn parse(&self, value: &str) -> Option<bool>

Parses a boolean literal using these options.

Parameters

• value - Candidate boolean literal.

Returns

Returns Some(bool) when the literal is recognized, or None otherwise.

Trait Implementations

impl Clone for BooleanConversionOptions

fn clone(&self) -> BooleanConversionOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BooleanConversionOptions

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

Formats the value using the given formatter.

impl Default for BooleanConversionOptions

fn default() -> Self

Creates default boolean conversion options.

impl PartialEq for BooleanConversionOptions

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

Tests for self and other values to be equal, and is used by ==.

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

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