Provide the number parser configuration. You will seldom use this directly. Instead, reference the current settings through a NumberParser instance.

Fields

permit_underscores: bool

Allow underscores in numbers. If this is true, then arbitrary underscores can occur in numbers, and these are dropped during parsing. If false, then underscores are not permitted.

permit_hexadecimal: bool

If true, methods that do not explicitly specify a radix will try to detect and parse hexadecimal numbers.

permit_octal: bool

If true, methods that do not explicitly specify a radix will try to detect and parse octal numbers.

permit_binary: bool

If true, methods that do not explicitly specify a radix will try to detect and parse binary numbers.

permit_plus: bool

If true, allow a number to start with a plus sign.

hexadecimal_indicator: Vec<char>

Specify the characters that indicate a hexadecimal value.

octal_indicator: Vec<char>

Specify the characters that indicate an octal value.

binary_indicator: Vec<char>

Specify the characters that indicate a binary value.

decimal_only_floats: bool

If true, floating point numbers can be in non-decimal radix.

permit_empty_whole: bool

If true, permit an empty whole part. That is, .15 is legal.

permit_empty_fraction: bool

If true, permit an empty fractional part. That is, 15. is legal.

permit_leading_zero: bool

If true, permit a leading zero for a non-zero whole. That is, 01.5 is legal.

NB: This only applies to decimal numbers, as leading zeros are common and expected in other bases.

Implementations

impl NumberParserSettings

pub fn new() -> Self

Make a new instance. The parsing rules are maximally permissive.

Trait Implementations

impl Clone for NumberParserSettings

fn clone(&self) -> NumberParserSettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumberParserSettings

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

Formats the value using the given formatter.

impl Default for NumberParserSettings

fn default() -> Self

Returns the “default value” for a type.
